Quantum-safe root-of-trust solution to secure ASICs, FPGAs

EDN Network - 4 години 12 хв тому

A new quantum-safe root-of-trust solution enables ASICs and FPGAs to comply with post-quantum cryptography (PQC) standards set out in regulations like the NSA’s CNSA 2.0. PQPlatform-TrustSys, built around the PQC-first design philosophy, aims to help manufacturers comply with cybersecurity regulations with minimal integration time and effort.

It facilitates robust key management by tracking the key’s origin and permission, including key revocation, an essential and often overlooked part of securing any large-scale cryptographic deployment. Moreover, root-of-trust enforces restrictions on critical operations and maintains security even if the host system is compromised.

Next, key origin and permission attributes are extended to cryptographic accelerators connected to a private peripheral bus. PQPlatform-TrustSys, launched by London, UK-based PQShield, has been unveiled after the company achieved FIPS 140-3 certification through the Cryptographic Module Verification Program (CMVP), which is designed to evaluate cryptographic modules and provide agencies and organizations with a metric for security products.

PQShield, a supplier of PQC solutions, has also built its own silicon test chip to prove this can all be delivered ‘first time right’. Its PQC solutions are developed around three pillars: ultra-fast, ultra-secure, and ultra-small.

PQShield’s security products are built around three basic tenets: ultra-fast, ultra-secure, and ultra-small.

The PKfail vulnerability has thrust multiple security issues within the secure boot and secure update domains, which play a fundamental role in protection against malware. Inevitably, ASICs and FPGAs will need to ensure secure boot and secure update while meeting both existing and new regulatory requirements with clear timelines set out by NIST.

Industry watchers believe that we have a five-to-10-year window to migrate to the PQC world. So, the availability of a quantum-safe root-of-trust solution bodes well for preparing ASICs and FPGAs to function securely in the quantum era.

Current monitor

EDN Network - 5 годин 12 хв тому

Almost every wall power supply has no indicator showing whether current is consumed by the load or not.

Wow the engineering world with your unique design: Design Ideas Submission Guide

It seems that this was a shortcoming that was not only noticed by me: I once saw the solution given in Figure 1.

Figure 1 Wall power supply indicator solution showing whether or not a current is being consumed by the load or not.

The thing is that the circuit was not functional—there were only places for the transistor, LED, and resistors on the board, not the elements themselves. It’s easy to say why: the voltage drop base-emitter (Vbe) is about 0.7 V, or 15% from the output voltage of this 5-V device. A monitor like this (Figure 1) would only be tolerable with a 12-V device or higher (24 V).

The circuit in Figure 2 is exceptionally good for low voltages, around 3 to 9 V, and for currents exceeding ~50 mA.

Figure 2 Current monitor circuit for a wall power supply that is good for voltages from 3 to 9 V and currents exceeding 50 mA.

It provides not only the opportunity to monitor its output current in a more efficient (30x) way, the bi-color LED allows it to estimate the value of the current and indicates the on-state of the device. Of course, the LEDs might be separate as well.

As for Q1, Q2: any low-power PNP with a reasonably high B will do, e.g., BC560.

Selective averaging in an oscilloscope

EDN Network - 5 годин 20 хв тому
Average of specific signal components

Sometimes, you only want to analyze those signal components that meet certain criteria or occur at certain times within an acquisition. This is not too difficult for a single acquisition, but what if you want to obtain the average of those selected measurement events? Here is where seemingly unrelated features of the oscilloscope can work together to get the desired data.

Consider an application where a device produces periodic RF pulse bursts, as shown in Figure 1.

Figure 1 The device under test produces periodic RF pulse bursts; the test goal is to acquire and average bursts with specific amplitudes. Source Arthur Pini

The goal of the test is to acquire and average only those bursts with a specific amplitude. In this case, those with a nominal value of 300 millivolts (mV) peak-to-peak. This desired measurement can be accomplished using the oscilloscope’s Pass/Fail testing capability to qualify the signal. Pass/Fail testing allows the user to test the waveform based on parametric measurements, like amplitude, and pass or fail the measured waveform based on it meeting preset limits. Alternatively, it can be tested by comparing the waveform to a mask template to determine if the waveform is within or outside of the mask. Based on the test results, many actions can be taken, from stopping the acquisition, storing the acquired waveform to memory or file, sounding an audible alarm, or emitting a pulse.

Selective averaging uses Pass/Fail testing to isolate the desired pulse bursts based on their amplitude or conformance to a mask template. Signals meeting the Pass/Fail criteria are stored in internal memory. The averager is set to use that storage memory as its source so that qualified signals transferred to the memory are added to the average.

Setting up Pass/Fail testing

Testing is based on the peak-to-peak amplitude, which uses measurement parameter P1. The measurement setup accepts or passes a pulse burst having a nominal peak-to-peak amplitude of 300 mV within a range of ±50 mV of nominal. The test limits are set up in test condition Q1 (Figure 2).

Figure 2 The initial setup to capture and average only pulses with amplitudes of 300 ± 50 mV. Source: Arthur Pini

The oscilloscope’s timebase is set to capture individual pulse bursts, in this case, 100 ns per division. This is important as only individual bursts should be added to the average. A single burst has been acquired, and its peak-to-peak amplitude is 334 mV, as read in parameter P1. The Pass/Fail test setup Q1 tests for the signal amplitude within ±50 mV of the nominal 300 mV amplitude. These limits are user-adjustable to acquire pulse bursts of any amplitude.

A single acquisition is made, acquiring a 338 mV pulse, which appears in the top display grid. This meets the Pass/Fail test criteria, and the signal is stored in memory M1 (Figure 3).

Figure 3 Acquiring a signal that meets the acceptance criteria adds a copy of the signal in memory M1 (center grid) and adds it to the averager contents (lower grid). Source: Arthur Pini

The memory contents are added to the average, showing a waveform count of 1. The Actions tab of the Pass/Fail setup shows that if the acquired signal passes the acceptance criteria, it is transferred into memory. The waveform store operation (i.e., what trace is stored in what memory) is set up separately in the Save Waveform operation under the File pulldown menu.

What happens if the acquired pulse doesn’t meet the test criteria? This is shown in Figure 4.

Figure 4 Acquiring a 247 mV burst results in a failed Q1 condition. In this case, the signal is not stored to M1 and is not added to the average. Source Arthur Pini

The acquired waveform has a peak-to-peak amplitude of 247 mV, outside the test limit. This results in a failure of the Q1 test (shown in red). The test action does not occur, and the low amplitude signal is not added to the average.

Using mask templates

Selective averaging can also be based on mask testing. Masks can be created based on an acquired waveform, or custom masks can be created using software utilities from the oscilloscope manufacturer and downloaded to the oscilloscope. This example uses a mask based on the acquired signal (Figure 5).

Figure 5 A mask, based on the nominal amplitude signal, is created in the oscilloscope. The acquired signal passes if all waveform samples are within the mask. Source Arthur Pini

The mask is created by adding incremental differences both horizontally and vertically about the source waveform. All points must be inside the mask for the acquired signal to pass. As in the previous case, if the signal passes, it is stored in memory and added to the average (Figure 6).

Figure 6 If the acquired signal is fully inside the mask, it is transferred to memory M1 and added to the average. Source Arthur Pini

If the acquired signal has points outside the mask, the test fails, and the signal is not transferred to memory or the average (Figure 7).

Figure 7 An example of a mask test failure with the circled points outside the mask. This waveform is not added to the average. Source Arthur Pini

Selective averaging with a gating signal

This technique can also be applied to signals on a multiplexed bus with a gating signal, such as a chip select, available (Figure 8). 

Figure 8 Pass/Fail testing can be employed to select only those signals that are time-coincident with a gating signal, such as a chip select signal. Source: Arthur Pini

The gating signal or chip select is acquired on a separate acquisition channel. In the example, channel 3 (C3) was used. The gating signal is positive when the desired signal is available. To add only those signals that coincide with the gating signal, pass/fail testing verifies the presence of a positive gating signal. Testing that the maximum value of C3 is greater than 100 mV verifies that the gate signal is in a high state, and the test is passed. The oscilloscope is set to store C1 in memory M1 under a passed condition, which is added to the average (Figure 9).

Figure 9 The average based on waveforms coincident with the gate positive gate signal state. Source: Arthur Pini

Isolating test signals

If the segments of the analyzed signal are close together and cannot be separated using the standard timebase (1,2,5 step) scales, a horizontal (zoom) expansion of the acquired signal can be used to select the desired signal segment part. The variable zoom scale provides very fine horizontal steps. The zoom trace can be used instead of the acquired channel, and the average source is the zoom trace.

Selective averaging

Selective averaging, based on Pass/Fail testing, is an example of linked features in an oscilloscope that complement each other and offer the user a broader range of measurements. Averaging was the selected analysis tool, but it could have been replaced with the fast Fourier transform (FFT) or a histogram. The oscilloscope used in this example was a Teledyne LeCroy HDO 6034B.

Portable power station battery capacity extension: Curious coordination

EDN Network - Срд, 04/23/2025 - 16:20

I’m still awaiting an opportunity, when I have spare time, the snow’s absent from the deck and winds are calm, to test out those two 220W solar panels I already mentioned I bought last year:

for parallel-combining and mating with my EcoFlow DELTA 2 portable power station:

While I remain on more-favorable-conditions standby, I’ve got two other pieces of EcoFlow gear also in the queue to tell you about. One, the 800W Alternator Charger that I mentioned in a more recent piece, isn’t an installation high-priority right now, so hands-on results prose will also need to wait.

But the other (and eventually also its replacement; hold that thought), which I pressed into service as soon as it arrived, is the topic of today’s post. It’s the DELTA 2 Smart Extra Battery, which mates to the DELTA 2 base unit over a thick dual-XT150-connectors-inclusive cable and combo-doubles the effective subsequently delivered storage capacity:

Here’s what my two identical-sized (15.7 x 8.3 x 11 in/400 x 211 x 281 mm) albeit different-weight (DELTA 2 base unit: 27 lbs/12 kg, DELTA 2 Smart Extra Battery: 21 lbs/9.5 kg) devices look like in their normal intended stacked configuration:

And here’s my more haphazard, enthusiastic initial out-of-box hookup of them:

In the latter photo, if you look closely, you can already discern why I returned the original Smart Extra Battery, which (like both its companion and its replacement) was a factory-refurbished unit from EcoFlow’s eBay storefront. Notice the brightness difference between it and the more intense DELTA 2’s displays. I should note upfront that at the time I took that photo, both devices’ screens still had the factory-installed clear plastic protectors on them, so there might have been some resultant muting. But presumably it would have dimmed both units’ displays equally.

The displays are odd in and of themselves. When I’d take a screen protector off, I’d see freakish “static” (for lack of a better word) scattered all over it for a few (dozen) seconds, and I could also subsequently simulate a semblance of the same effect by rubbing my thumb over the display. This photo shows the artifacts to a limited degree (note, in particular, the lower left quadrant):

My root-cause research has been to-date fruitless; I’d welcome reader suggestions on what core display technology EcoFlow is using and what specific effect is at play when these artifacts appear. Fortunately, if I wait long enough, they eventually disappear!

As for the defective display in particular, its behavior was interesting, too. LCDs, for example, typically document a viewing angle specification, which is the maximum off-axis angle at which the display still delivers optimum brightness, contrast and other attributes. Beyond that point, typically to either side but also vertically, image quality drops off. With the DELTA 2 display, it was optimum when viewed straight on, with drop-off both from above and below. With the original Smart Extra Battery display, conversely, quality was optimum when viewed from below, almost (or maybe exactly) as if the root cause was a misaligned LCD polarizer. Here are closeups of both devices’ displays, captured straight on in both cases, post-charging:

After checking with Reddit to confirm that what I was experiencing was atypical, I reached out to EcoFlow’s eBay support team, who promptly and thoroughly took care of me (and no, they didn’t know I was a “press guy”, either), with Fedex picking up the pre-paid return-shipping defective unit at my front door:

and a replacement, quick-shipped to me as soon as the original arrived back at EcoFlow.

That’s better!

The Smart Extra Battery appears within the app screens for the DELTA 2, vs as a distinct device:

Here’s the thick interconnect cable:

I’d initially thought EcoFlow forgot to include it, but eventually found it (plus some documentation) in a storage compartment on top of the device:

Here are close-ups of the XT150 connectors, both at-device (the ones on the sides of the DELTA 2 and Smart Extra Battery are identical) and on-cable (they’re the same on both ends):

I checked for available firmware updates after first-time connecting them; one was available.

I don’t know if it was related to the capacity expansion specifically or was just timing-coincidental, and if it was for the DELTA 2 (with in-progress status shown in the next photo), Smart Extra Battery or both…but it completed uneventfully and successfully.

Returning to the original unit, as that’s what I’d predominantly photo-documented, it initially arrived only 30% “full”:

With the DELTA 2 running the show, first-time charging of the Smart Extra Battery was initially rapid and high power-drawing; note the incoming power measured at it:

and flowing both into and out of the already-fully-charged DELTA 2:

As the charging process progressed, the current flow into the Smart Extra Battery slowed, eventually to a (comparative) trickle:

until it finished. Note the high reported Smart Extra Battery temperature immediately after charge completion, both in an absolute sense and relative to the normal-temperature screenshot shown earlier!

In closing, allow me to explain the “Curious Coordination” bit in the title of this writeup. I’d upfront assumed that if I lost premises power and needed to harness the electrons previously collected within the DELTA 2/Smart Extra Battery combo instead, the Smart Extra Battery would be drained first. Such a sequence would theoretically allow me to, for example, then disconnect the Smart Extra Battery and replace it with another already-fully-charged one I might have sat around to further extend the setup’s total usable timespan prior to complete depletion.

In saying this, I realize that the feasibility of such a scenario isn’t likely, since the Smart Extra Battery can’t be charged directly from AC (or solar, for that matter) but instead requires an XT150-equipped “smart” source such as a (second, in this scenario) DELTA 2. That said, what I discovered to be the case when I finally got the gear in my hands was the exact opposite; the DELTA 2 battery drained first, down to a nearly (but not completely) empty point, then the discharge source switched to the extra battery. And that said, further research has educated me that actual behavior varies depending on how much current is demanded by whatever the combo is powering; in heavy-load scenarios, the two devices’ battery packs drain in parallel.

What are your thoughts on this behavior, and/or anything else I’ve mentioned here? Share them with your fellow readers (and me!) in the comments!

New radar sensor with Bosch’s own computing chip (SoC) and flexible ADAS solution packages

  • The Bosch ADAS product family is a flexible modular system for driver assistance. Bosch is to equip the first passenger cars in China from mid-2025.
  • Bosch is the first Tier 1 supplier to present a new radar sensor with a complete in-house design and its own system-on-chip (SoC).
  • The future portfolio for driver assistance and automated driving is rounded off by a next-generation multi-purpose camera and inertial sensor unit.

Bosch is presenting its extensive portfolio of solutions for assisted and automated driving and parking. It includes software features and hardware components that the technology group is aligning with the expectations of local drivers and can be easily customized for different customer needs. With its radar sensor, Bosch is the first Tier 1 supplier worldwide to break new ground and develop and manufacture the entire product in-house. The special feature: The sensor has a computing chip specially developed by Bosch–known as an SoC–which combines high computing power with the smallest possible footprint. The radar sensor fits into Bosch’s newly designed modular system for assisted and automated driving: The Bosch ADAS product family (Advanced Driver Assistance Systems) offers a kind of ecosystem of software, sensors and services as well as the appropriate high-performance computers. Customers can make use of this and flexibly utilize the comprehensive solutions for various markets and vehicle segment – from low-cost small cars to high-performance premium models. The goal: Bosch wants to enable manufacturers worldwide to bring driver assistance functions to the mass market more easily, quickly, and cost-effectively. A new generation of the multi-purpose camera and the inertial sensor unit for the precise localization of assisted and automated vehicles complement the sensor portfolio.

“With our new Bosch ADAS product family, we are offering cost-efficient solutions for assisted and automated driving to the usual high standards of quality and safety. We have the right software and hardware for driver assistance functions, from small cars to mid segment and premium vehicles. This enables car manufacturers to integrate functions quickly and easily into their vehicles and bring them to market very fast.”

New Bosch ADAS product family in three equipment variants

Advanced driver assistance systems help to increase safety and comfort on the road. For example, by providing the driver with targeted support during monotonous and tiring driving tasks. Bosch has many years of experience with driver assistance systems, their development and integration into the vehicle. A deep understanding of each vehicle area is required for optimum implementation. With this expertise, Bosch is repositioning the ADAS product family. It enables assisted driving and parking up to SAE level 2, thus meeting the prevailing demand on the market. Bosch offers the ADAS product family in three variants: for the entry segment, the mid segment and the high segment. The variants differ depending on the scope of the software, the number and combination of sensors, and the required computing power. Seamless harmonization of these individual components facilitates system integration. Bosch gives car manufacturers swift and uncomplicated access to driver assistance systems, enabling them to significantly accelerate the development time of their vehicles. Bosch brings its hardware and software components to the market both as a complete systemic solution and separately from each other, as is the case in modern vehicle development. This provides further scope, as individual components of the three variants can be exchanged and flexibly combined as required. Accordingly, manufacturers have further freedom to integrate the driver assistance systems into their cars on a brand-specific basis. Artificial intelligence can be found throughout the Bosch ADAS product family. Bosch uses it, for example, for perception and driving planning. Thanks to AI, the vehicle thinks ahead, pays attention to what other road users might be doing, and calculates the next steps to safely reach the destination.

The entry segment version already incorporates key safety and comfort functions into the vehicle. The car uses this to regulate its speed and distance from the vehicle in front depending on the situation and keeps in lane when lane markings are clearly visible. This variant can be implemented as a purely camera solution with the new multi-purpose camera from Bosch, but can also be supplemented with up to five radar sensors depending on the safety requirements (of a country). The variant for the mid segment unlocks even more extensive functions. For example, an extended lane keeping assist that can also cope with lane markings that are not visible in places. In this variant, Bosch combines its camera heads for perception with additional sensors. The computing power no longer takes place in the camera itself, but in a more powerful central vehicle computer, as is becoming standard in software cars. Thanks to Bosch, the vehicle masters more complex traffic scenarios, which further increases driving comfort and safety on freeways and in heavy traffic. The system also pays attention and supports the driver. Bosch is already introducing hands-free driving on the freeway in this variant, provided the legal framework in the respective country permits it. This means that the driver can take their hands off the steering wheel at times, but still remains responsible. The variant for the high segment represents the pinnacle of Bosch driving assistance. It uses a 360-degree video belt and impresses with even greater computing power, so that the vehicle can handle urban junctions with ease and safely enter and exit roundabouts. Hands-free driving is extended to urban traffic in this version, provided that the legal requirements in the markets allow it. Bosch takes into account the various regulatory requirements and safety assessments

Bosch ADAS product family goes into serial production in mid-2025

The equipment variant for the mid-range segment will go into serial production with a Chinese manufacturer in the middle of this year. Users of this system will benefit from an assistance system linked to the navigation system, which is particularly popular among Chinese customers. The vehicle then independently carries out driving maneuvers along the route entered, such as changing lanes on freeways. The driver remains responsible and must be ready to intervene at any time. This function makes driving in the heavy traffic of Chinese cities more convenient and safer. Bosch has also already secured its first orders for the high segment version, with serial production expected to start in summer 2025. Bosch has already acquired half a dozen new customers for the ADAS product family for mid- and high segment in China, including BAIC, Dongfeng and Jetour. Bosch is thus continuously strengthening its leading position in the global ADAS market.

New radar sensor with Bosch SoC

Radar sensors are key components of driver assistance systems and modern vehicles would be inconceivable without them. For the new generation of its radar sensor, Bosch has developed and manufactured all core elements in-house, including the computing chip (SoC). The new Bosch radar sensor uses “RF CMOS technology,” which enables the efficient integration of high-frequency and digital circuits on a single chip. The structure size of the transistors of only 22 nanometers makes the chip particularly powerful and efficient despite its small footprint. Bosch is the first Tier 1 supplier on the market to introduce this technology in serial production.

New generation of the multi purpose camera

With the increasing market penetration of more extensive driver assistance functions in the lower price segments, high-performance yet affordable camera solutions are steadily gaining in importance. The new multi purpose camera from Bosch enables assisted driving and parking functions (up to SAE level 2) from the entry segment. Serial production is scheduled to start in 2026, initially in the Chinese market. Bosch’s own optical image processing module in the new camera generation ensures optimum sharpness and precision over the entire product service life, even in highly fluctuating temperatures. The camera is particularly durable, with consistently stable functional performance.

With its 8 megapixel image sensor, a horizontal field of vision of 120 degrees, and a detection range of up to 300 meters, the camera enables safety and convenience functions for assisted driving. These include adaptive cruise control and distance control, emergency braking within your own lane, lane keeping in urban areas, and detection and stopping at red lights

The new multi purpose camera is the central interface for the fusion of various sensor data. This means that the camera combines the data from its own image sensor and additionally from up to five radars and other sensors such as driver monitoring cameras or interior sensors. This integrated approach enables OEMs to reliably comply with mandatory ADAS regulations (e.g. General Safety Regulation), improve driving safety, and support the driver on the freeway (e.g. with assisted lane changes).

Safe localization in all driving situations

For assisted and automated driving, it is essential that vehicles can locate themselves precisely and safely at all times. Even in difficult visibility conditions and in the absence of lane markings or if the signal from the global navigation satellite system (GNSS) fails – for example, when driving through a tunnel – it is essential that the vehicle’s location can be determined reliably. This is the only way to guarantee a high level of functional availability. At the largest automotive trade fair in China, Bosch is presenting for the first time the new generation of its high-performance inertial measurement unit (IMU), which has been specially designed for ADAS and vehicle dynamics applications. Vehicles pitch when braking, lean to one side (roll) or lurch (swerve) when taking corners. In addition to these movements, the inertial sensor unit measures the vertical, longitudinal and lateral acceleration of the vehicle. From this, it can precisely calculate the relative change in position of the vehicle, enabling it to maintain the originally planned route with only minimal deviation. With various product variants, Bosch offers a high degree of scalability, from the cost-effective entry segment variant for assisted driving to the high-performance sensor for automated driving up to SAE level 4. Bosch uses sensor modules that are manufactured in the company’s own production facilities and, in addition to an in-depth understanding of the system, can draw on a comprehensive range of experience from over three decades of developing such inertial sensors.
