In the ever-expanding digital landscape, the terms “cybersecurity” and “ethical hacking” often get tossed around interchangeably. While both disciplines share a common goal – protecting our valuable data and systems from malicious actors – their approaches and objectives diverge significantly. Understanding these distinctions is crucial for navigating the complex terrain of the digital frontier.

Cybersecurity: Building the Fortress

Cybersecurity can be likened to a meticulously constructed fortress, safeguarding our digital assets from unauthorized access, theft, disruption, modification, or destruction. It encompasses a comprehensive set of strategies, technologies, and practices designed to deter, detect, and mitigate cyberattacks.

• Defense in Depth: Cybersecurity professionals employ a layered defense approach, akin to building multiple walls around a castle. This includes firewalls, intrusion detection/prevention systems (IDS/IPS), data encryption, access controls, and user education. Each layer serves as a barrier, making it progressively harder for attackers to breach the system.
• Continuous Monitoring: Vigilance is paramount in cybersecurity. Security professionals constantly monitor network activity, system logs, and user behavior for anomalies that might indicate a potential attack. Security Information and Event Management (SIEM) systems play a vital role in this ongoing process, aggregating data from various sources and providing real-time insights into potential threats.
• Incident Response: Despite the best-laid plans, cyberattacks can still occur. Cybersecurity professionals develop and implement incident response plans to effectively respond to security breaches. These plans outline procedures for containing the damage, eradicating the threat, and restoring affected systems.

Ethical Hacking: Testing the Walls

Ethical hacking, on the other hand, embodies a proactive approach to cybersecurity. Ethical hackers, also known as white hat hackers or penetration testers, are security professionals who are authorized to simulate cyberattacks on a system or network. Their objective is to identify vulnerabilities that malicious actors might exploit and recommend appropriate security measures to address them.

• Vulnerability Assessment and Penetration Testing (VAPT): This is the cornerstone of ethical hacking. Ethical hackers employ a variety of tools and techniques, mirroring those used by real-world attackers, to probe for weaknesses in systems and networks. They may attempt to gain unauthorized access, exploit software vulnerabilities, or bypass security controls.
• Social Engineering Assessments: Ethical hackers don’t just focus on technical vulnerabilities. They also assess the human element of security by conducting social engineering simulations. This involves mimicking tactics used by attackers, such as phishing emails or pretext calls, to evaluate employee awareness and susceptibility to social engineering attacks.
• Red Teaming and Purple Teaming: Ethical hacking can be taken a step further through red teaming and purple teaming exercises. Red teaming exercises simulate a full-blown cyberattack, allowing organizations to assess their overall security posture and response capabilities. Purple teaming exercises involve collaboration between ethical hackers and security teams, fostering communication and knowledge sharing to strengthen the organization’s defenses.

The Synergy Between Cybersecurity and Ethical Hacking

While cybersecurity and ethical hacking operate on different sides of the digital security spectrum, they share a symbiotic relationship. Cybersecurity professionals rely on the insights gleaned from ethical hacking to identify and address vulnerabilities before they can be exploited by malicious actors. Ethical hackers, in turn, depend on a strong understanding of cybersecurity principles and best practices to effectively simulate real-world attacks.

Key Distinctions: A Comparative Analysis

• Objectives: Cybersecurity aims to defend systems and data from unauthorized access and attacks. Ethical hacking, on the other hand, proactively identifies vulnerabilities in systems to improve security posture.
• Methodology: Cybersecurity professionals employ a defensive approach, deploying security tools and monitoring systems for suspicious activity. Ethical hackers take an offensive stance, simulating attacks to uncover vulnerabilities.
• Legality: Cybersecurity activities are always legal and authorized. Ethical hacking is legal only when conducted with explicit permission from the system or network owner.
• Outcomes: Effective cybersecurity practices minimize the risk of cyberattacks. Ethical hacking identifies vulnerabilities that can be addressed to strengthen overall security.

The Evolving Landscape: The Rise of Bug Bounties

The recognition of the value of ethical hacking has led to the emergence of bug bounty programs. These programs incentivize security researchers to identify and report vulnerabilities in software or systems. Organizations can leverage these programs to discover and address vulnerabilities before they are exploited by malicious actors.

Conclusion: A United Front in the Digital Age

Cybersecurity and ethical hacking, though distinct disciplines, are both essential components of a comprehensive digital security strategy. By combining the proactive vulnerability identification of ethical hacking with the defensive measures of cybersecurity, organizations can create a robust and innovative security ecosystem that can adapt to the rapidly changing threat landscape and safeguard our increasingly interconnected digital world.

As ST recently released X-CUBE-MCSDK 6.3.2, let us delve into its firmware libraries and its Graphical User Interface (GUI) to see how it can help create motor control applications. Designed for permanent magnet synchronous (PMSM) and BLDC motors using FOC (Field-oriented control) or 6-steps, it has gained popularity since we launched it in 2018 because it helps engineers bring their solutions to market faster. For instance, the algorithms from ST will maximize efficiency and facilitate the implementation of critical features like on-the-fly startup for air conditioning fans, a single shunt for cost-effective solutions, flux weakening for washing machines, and a rotor’s angular position detection for sensorless applications.

X-CUBE-MCSDK: Latest highlights HSO

Over the years, X-CUBE-MCSDK has received new algorithms that have changed what is capable on BLDC motors and PMSM, such as HSO or high-sensitivity observer. In a nutshell, HSO is a field-oriented control algorithm that enables an application to figure out the rotor’s position and speed without needing a sensor. It’s particularly useful with PMSM sensorless motors running at low speeds in home appliances, for instance, because cost is such a critical factor. To attract new customers, manufacturers must lower their bill of materials, which means doing away with sensors and using more cost-effective MCUs, like an STM32G4. By using HSO, engineers can meet those constraints.

ZeST

ZeST (zero-speed full torque) is another algorithm meant to optimize the operations of sensorless motors by enabling them to recover from a complete stop. Combined with HSO, it can detect when a motor is no longer rotating and immediately resume operations. Accordingly, since most applications don’t need to know if a motor has ceased turning, most developers will only need to use HSO, which has been available in X-CUBE-SDK since version 6.2. However, engineers working on applications that could use ZeST can reach out to their local ST representative and seek to enable the STM32 ZeST and implement the feature in their application.

The idea behind HSO and ZeST isn’t new, and more seasoned engineers will be familiar with the phase-locked loop (PLL) observer, a technique (also found in X-CUBE-MCSDK) that determines the rotor position and speed without a sensor. However, combining HSO and ZeST helps alleviate some of PLL’s shortcomings, such as its inability to work under a minimum motor speed. Additionally, HSO and ZeST take advantage of the STM32G4 to run without maximizing CPU usage, despite how advanced these algorithms are. HSO and ZeST also have a shorter start-up time and do not generate high peak current, resulting in an energy saving between 15% and 40% in a typical washing machine application.

Regular updates

X-CUBE-MCSDK receives regular updates. Before version 6.3.1 in September 2024, we launched version 6.3 in May 2024, which brought support for new MCUs, like the STM32C0, our new entry-level device, and new STSPIN32 devices like the STSPIN32G4. It also added a new Board Designer tool and the ability to spec user boards using JSON to simplify developments. And while all versions of X-CUBE-MCSDK are mindful of legacy support, previous versions have also brought new features like BLCD six-step motors, monitoring, and profiling. Put simply, X-CUBE-MCSDK is a unique way to create motor control applications because it demystifies complex notions and makes modern algorithms and development paradigms more accessible.

X-CUBE-MCSDK and its robust firmware architecture Motor Control Libraries now based on STM32Cube

A significant advantage of the new SDK resides in the use of a different programming paradigm to ensure developers get a code that is a lot easier to customize and debug. Before X-CUBE-MCSDK, certain aspects of our libraries used object-oriented concepts inherited from C++. We rewrote them to something more approachable in C to simplify application development. For example, we no longer cast some expressions to void, a popular method in C++ to suppress compiler warnings, but that tends to complicate debugging operations drastically. Porting libraries to C also helped optimize applications as teams can more easily improve performance and efficiency.

X-CUBE-MCSDK was thus a major internal overhaul accompanied by massive updates to our SDK’s libraries. Indeed, previous versions used older code that was no longer standard on STM32 MCUs. STM32Cube is the de facto solution for all developments on our microcontrollers. It offers Hardware Abstraction Layers (HAL), increases portability between STM32 MCUs, and offers low-level APIs, drivers, and other Middleware components to make the ST ecosystem more accessible and efficient. X-CUBE-MCSDK brought the same standard libraries, so developers familiar with STM32Cube could have a much easier time with the code and reuse a significant chunk of their application from one project to the next.

X-CUBE-MCSDK and its flexible GUI Interface of STM32CubeMX

Aside from internal modifications that may not always be obvious, the new SDK works in conjunction with STM32CubeMX. Indeed, X-CUBE-MCSDK still uses MC-Workbench, a graphical tool where engineers can enter their motor and sensors’ parameters to generate custom code for their setup. When developers want to change the preselected configuration, such as the STM32 part number, the pinout configuration, the clock configuration, or add peripherals for new communication interfaces, they can more easily generate a new code for their application by using STM32CubeMX. They are also free to customize projects and add custom code (extra PID control loop, for instance) within tags created by STM32CubeMX.

The ST Community is fond of the STM32CubeMX configuration tool because it uses STM32Cube libraries and an intuitive interface to quickly generate header files, taking complex design operations out of developers’ hands. Using a step-by-step process, it’s easy to configure pinouts, clock trees, and peripherals, as well as resolve conflicts, among other things. If designers working on a motor control application decide to use another MCU in the middle of their prototyping phase, they will merely need to open STM32CubeMX, and will much more quickly port the work done on the previous MCU. X-CUBE-MCSDK thus brought a new level of flexibility.

ST teams are already working on the next updates. In the meantime, the best way to start working on a motor control solution is to check out our dedicated Wiki and ask questions on our Community forum. The Wiki will guide users by showing them how to run example applications on ST development boards to hasten prototyping. It’s also a quick way to see how we implemented our libraries and can thus serve as the basis for a project. For instance, the page on the six-step algorithm helps engineers with less experience understand what is happening while also providing a walkthrough of the GUI and compatible boards.

Whether its buck, boost, or buck/boost, internal or external switch, milliamps or tens of amps, a literal cornucopia of programmable output switching regulator/converter chips are commercially available. While the required external Ls and Cs (of course) vary wildly from topology to topology and chip to chip, (almost) all use exactly the same basic two-resistor network for output voltage programming shown in Figure 1. Its example buck type regulator was picked more or less arbitrarily, so please ignore the L and Cs and just focus on R1, R2, and (later) R3.

Figure 1 The (almost) universal regulator output programming network where Vout = Vsense(R1/R2 + 1) = 0.8v*(11.5 + 1) = 10v.

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

For reasons known only to gurus of the mystic and marvelous monolithic realm, the precision Vsense feedback node voltage varies from type to type over a roughly 3:1 range from 0.50v to 1.5v. Recommended values for R1 vary too. 

The point is the topology doesn’t vary. All (or at least most) conform faithfully to Figure 1. This surprising uniformity becomes very useful if your application requires DAC control of the output voltage. See Figure 2 for how this can be done with a positive polarity DAC and just one added resistor: R3.

Figure 2 Regulator output programming with a DAC and the KISS1 network where Vout = (Vc)*(R1/R2) = (2.5 to 0v) 4 = 0 to 10v.

Given reasonable choices for the DAC (e.g., 2.5v), numbers for R1 and Vsense from the regulator chip datasheet, and Vomax from your application requirements, here’s the KISS1 arithmetic:

1. R2 = R1 Vcmax/Vomax
2. R3 = R1/(Vomax/Vsense – R1/R2 – 1)

And, in the grand tradition of the KISS1 principle, that’s it. Ok, ok. Except maybe for a couple of (minor?) caveats. For example:

1. Expression 2 above, and therefore the necessary value for R3, must shake out positive. I can’t think of a practical case where it wouldn’t, but there’s probably some perverse permutation of parameters out there where it won’t, and implementing negative resistors isn’t particularly simple.
2. The relation between Vout and Vc is inverse. So, the digital version of Vc must be 1’s complemented (a totally KISS-bit of software arithmetic to flip all the bits, so 0s become 1s, and 1s become 0s) before being written to the DAC register.
3. Vin must be adequate for the chosen chip to generate the chosen Vomax when Vc = 0. Duh.

So maybe it’s not really totally KISS1, just mostly.

My first isolated power supply!! It does 200mA fused, +-9V. The actual max current is a mystery due to the salvaged transformer (from a device that is at around 3 times as old as me), so I took a relatively conservative guess. t's fully linear, with less than 1mV PARD at full load (using a very janky test setup though). I have a higher power (1.25-18V, 0-3A) power supply made of a buck regulator module with a laptop power supply, but it not isolated, and the ripple is horrible. I only made this so that I could test parts of my next power supply, which will be a more legit, 0-20V, 0-2A lab power supply. I'm going to box it up later, but for now it does work. submitted by /u/Triq1 [link] [comments]

DC-to-DC converters are electronic devices that change one DC voltage level to another. They are widely used in power supplies for electronic devices, electric vehicles, and renewable energy systems. Here are the main types:

1. Linear Regulators:
   • Simple and cost-effective.
   • Converts excess voltage into heat, making them inefficient for large voltage differences.
   • Example: Low Dropout Regulators (LDO).
2. Switching Converters:
   • Efficient and suitable for large voltage differences.
   • Types:
     • Buck Converter (Step-Down):
       • Reduces input voltage to a lower output voltage.
     • Boost Converter (Step-Up):
       • Increases input voltage to a higher output voltage.
     • Buck-Boost Converter:
       • Can increase or decrease voltage depending on the configuration.
     • Cuk Converter:
       • Provides an inverted output voltage and regulates it.
     • SEPIC (Single-Ended Primary Inductor Converter):
       • Allows for voltage output either higher or lower than the input.
     • Flyback Converter:
       • Common in isolated power supplies for low-power applications.
     • Push-Pull Converter:
       • Symmetrical design for higher power and efficient isolation.
3. Charge Pump Converters:
   • Use capacitors for energy storage and voltage conversion.
   • Lightweight and efficient for low-power applications.
4. Isolated Converters:
   • Separate the input and output using transformers or optocouplers for safety.
   • Examples: Flyback and Forward Converters.

DC-to-DC Conversion Formula

The power balance principle is used to derive relationships in DC-to-DC converters. The formulas vary based on the converter type:

DC-to-DC Converter Examples

1. Consumer Electronics:

This product contributes to the miniaturization and cost reduction of optical systems. Additionally, when combined with our mass-produced ultraviolet semiconductor lasers (378 nm) and violet semiconductor lasers (402 nm), it serves as an alternative light source solution to mercury lamps, contributing to the realization of a sustainable society.

(*) As of January 15, 2025, based on our research of semiconductor lasers emitting at a wavelength of 420 nm.

Achievements:

• Achieves industry-leading optical output power of 1.7 W at a wavelength of 420 nm, contributing to increased design flexibility and miniaturization of optical systems.
• Realizes high efficiency and long-term reliability through proprietary optical design and heat dissipation technology, reducing the running costs of optical systems.
• By combining this product with existing mass-produced products, it is possible to provide alternative light source solutions to mercury lamps.

Mercury lamps emit bright lines of light such as the i-line (365 nm), h-line (405 nm), and g-line (436 nm) [2], and are used as industrial light sources for applications such as resin curing and exposure. However, the mercury lamps have technical challenges including large light source size and high power consumption. Additionally, since they use mercury, mercury lamps are subject to regulations in Japan and other countries because of health and environmental concerns. Therefore, alternative light sources are expected to be developed.

Aiming to replace the mercury lamps, we have been developing high-efficiency and long-term reliability semiconductor lasers. We have now started mass production of an industry-leading indigo semiconductor laser with an optical output power of 1.7 W at a wavelength of 420 nm, close to the g-line of the mercury lamps. This new product achieves both high efficiency and long-term reliability through proprietary optical design and heat dissipation technology. Furthermore, by combining it with our already mass-produced ultraviolet semiconductor lasers (378 nm) and violet semiconductor lasers (402 nm), we can provide alternative light source solutions to the mercury lamps, contributing to the realization of a sustainable society.

Details of the new product and alternative light source solutions to the mercury lamps will be exhibited at our booth at SPIE Photonics West 2025 in San Francisco, USA, and LASER World of PHOTONICS 2025 in Munich, Germany. We look forward to welcoming you.

Features:

• Achieves industry-leading optical output power of 1.7 W at a wavelength of 420 nm, contributing to increased design flexibility and miniaturization of optical systems.

This product achieves an industry-leading optical output power of 1.7 W at a wavelength of 420 nm, close to the g-line of mercury lamps, in a compact TO-56 CAN package [3]. Using this high-output, compact product enhances the design flexibility of light source devices, enabling the development of smaller light source devices compared to the mercury lamps.

• Realizes high efficiency and long-term reliability through proprietary optical design and heat dissipation technology, reducing the running costs of optical systems.

With over 40 years of experience and more than 3 billion semiconductor lasers shipped for optical discs, we have developed extensive design and manufacturing expertise in semiconductor lasers. Our newly developed indigo semiconductor laser integrates proprietary optical design and heat dissipation technology, achieving both high efficiency and long-term reliability. Compared to the mercury lamps, this reduces power consumption and the frequency of light source replacements, thereby lowering the running costs of light sources.

• By combining this product with existing mass-produced products, it is possible to provide alternative light source solutions to mercury lamps.

This product, which emits laser light at a wavelength of 420 nm close to the g-line of mercury lamps, can be combined with our mass-produced ultraviolet semiconductor lasers (378 nm) and violet semiconductor lasers (402 nm) to serve as alternative light sources for the i-line (365 nm), h-line (405 nm), and g-line (436 nm) of mercury lamps. Additionally, by adjusting the output power ratio of each semiconductor laser according to the application, it is possible to achieve highly flexible optical designs that were not possible with the mercury lamps.

Bluetest and Rohde & Schwarz extend their long-established collaboration and have integrated the Wi-Fi 7 test functionality of the R&S CMX500 one-box signaling tester into the Bluetest Flow control software. Now, developers and manufacturers of next-generation WLAN technology can use the Bluetest reverberation test systems (RTS) to perform MIMO stress testing of IEEE 802.11be stations as well as access points under realistic conditions.

Bluetest specializes in reverberation chambers, such as the RTS65, which are designed for efficient over-the-air performance evaluation of wireless devices. In contrast to anechoic test chambers, reverberation chambers extensively reflect an RF signal inside the chamber, creating a Rayleigh faded multipath RF environment. This environment closely mirrors real-world indoor and city conditions, making it ideal for evaluating the antenna and radio performance of modern multi-antenna (MIMO) and multi-carrier devices as used in WLAN, 4G, and 5G.

The setup is operated using the Bluetest Flow control software, an integrated test environment for complex wireless solutions. By integrating the Wi-Fi 7 test functionality of the R&S CMX500 one-box signaling tester into the Bluetest Flow software, WLAN developers utilizing the R&S CMX500 can now leverage Bluetest’s reverberation chamber technology in the development of their advanced WLAN stations and access points.

Wi-Fi 7 (IEEE 802.11be) is engineered for extremely high data throughput and capable of handling tens of gigabits of data per second with low latency. It caters to the increasing demand for ultra-high-definition video streaming, virtual reality, and augmented reality applications. The key components facilitating higher throughput include an increased channel bandwidth of 320 MHz, up to 16 spatial streams, 4096 QAM modulation, and multi-link operation (MLO).

During the development of WLAN devices, measurements of the antennas as well as RF transmitter and receiver characteristics must be conducted under real-world conditions in signaling mode. With MLO being a key feature in Wi-Fi 7, a test environment that provides multiple RF chains is crucial. The R&S CMX500 one-box tester from Rohde & Schwarz, featuring integrated Wi-Fi 7 test functionality, is a multi-technology multi-channel signaling tester. Its flexibility, support for multiple radio technologies, and embedded IP test capabilities make it a versatile solution for a broad range of Wi-Fi 7-specific tests.

Christoph Pointner, Senior Vice President of Mobile Radio Testers at Rohde & Schwarz, said: “Our collaboration with Bluetest has resulted in a unique synergy between our CMX500 one-box tester and their RTS technology. This long-established partnership has enabled us to push the boundaries of WLAN testing, providing a real-world environment that is integral to the development of cutting-edge wireless solutions.”

Kjell Olovsson, Bluetest CEO, said: “Teaming up with Rohde & Schwarz and integrating their CMX500 one-box tester into our Flow software broadens our WLAN testing capabilities. Now we are able to offer an unprecedented testing environment for the latest Wi-Fi 7 devices, reflecting our commitment to supporting the evolution of wireless communication.”
