An off-the-shelf secure authentication IC combined with cloud-based security software-as-a-service (SaaS) claims to manage and update embedded security credentials in the field instead of being limited to a static certificate chain implemented during manufacturing.

Microchip’s ECC608 TrustMANAGER authentication ICs are paired with Kudelski IoT’s keySTREAM device-to-cloud solution for securing key assets end-to-end in an IoT ecosystem throughout a product’s lifecycle. The combo enables custom cryptographic credentials to be accurately provisioned at the endpoint without requiring supply chain customization and can be managed by the end user.

ECC608 TrustMANAGER, a secure authentication IC designed to store and protect cryptographic keys and certificates, is managed by the keySTREAM SaaS. Their combination allows end users to set up a self-serve root Certificate Authority (root CA). Next, the associated public key infrastructure (PKI) secured by Kudelski IoT creates and manages a dynamic certificate chain and provisions devices in the field the first time they are connected.

Once claimed in the SaaS account, the IoT devices are automatically activated in the user’s keySTREAM service via in-field provisioning. In other words, security ICs like ECC608 TrustMANAGER come with a pre-provisioned set of keys that will be controlled by keySTREAM at the time the IoT device connects for the first time.

The operation—called in-field provisioning of the PKI— happens in-field, and after in-field provisioning, the fleet of devices containing the ECC608 TrustMANAGER is first claimed and then activated in the user’s keySTREAM account.

An IoT device is “claimed” when the purchased batch of security ICs shows up in the keySTREAM account but not connected yet. It’s “activated” when the purchased batch of security ICs is connected to keySTREAM and the in-field provisioning takes place.

It’s a pivotal moment in the industry’s quest to secure the IoT landscape and make provisioning easier. Especially when the volume of connected devices rapidly increases, and security standards and regulations steadily tighten.

Moreover, security standards and upcoming regulations increasingly require the upgradability of security infrastructure for IoT devices. This poses a dilemma for traditionally static IoT security implementations, which require physical upgrades like changing out the security ICs in each device to stay in compliance.

The combo of silicon components and key management SaaS automates provisioning and facilitates easy device ownership management without changing hardware. It also streamlines the supply chain processes for distribution partners.

Hello everyone, could someone tell me where I found the datasheet for this module "Mitsubishi J2-Q03A-D" I can't find it on the Web, very possible it's an IGBT, I want to know what's burnt too Thanks submitted by /u/bil7200 [link] [comments]

It even comes with a light if it's too dark. Incredible! submitted by /u/Desperate_Original56 [link] [comments]

It may look small (ring for scale) but it sure is mighty with a max volume of 110db. I 3d printed a case too. What do you think? submitted by /u/AlbertoIsExpired [link] [comments]

Microchip has added its ECC608 TrustMANAGER with Kudelski IoT’s keySTREAM software as a service (SaaS) to its Trust Platform of devices, services, and tools. The cloud-based key-management SaaS integrates with the ECC608 secure authentication IC to increase the security of IoT network-connected products. It also simplifies setup and lifecycle management.

The ECC608 TrustMANAGER IC stores and protects cryptographic keys and certificates, which are then managed and updated in the field via keySTREAM. This combination allows the setup of a self-serve root Certificate Authority and associated public key infrastructure (PKI). Users can create and manage a dynamic certificate chain and provision devices in the field the first time they are connected.

The ECC608 is the first security IC in the TrustMANAGER series. To get started, download the Trust Platform Design Suite and test the KeySTREAM use case under the ECC608.

Prices for the ECC608 TrustMANAGER start at $0.75 each in lots of 10,000 units. An activation fee is applied only after the device has been connected for the first time.

A multichannel oscilloscope calibration system, the Fluke 9500C automates time-consuming testing to maintain scope accuracy and reliability. The 9500C provides simultaneous output on all channels and can be fully automated with MET/CAL software for hands-free operation.

A core component of the 9500C mainframe is the 9540C active head. Each mainframe can control up to five heads, enabling the calibration of a 4-channel oscilloscope with an external trigger. The ability to actively drive all four active heads at the same time with simultaneous output results in faster test times and eliminates lead changes.

The compact 9.4×4.6×2.2-cm active head generates calibration signals at the oscilloscope input. It enables the 9500C to deliver various signals: DC levels up to ±220 V, calibrated amplitude square waves up to 210 V pk-pk from 10 Hz to 100 kHz, and leveled sinewaves from 0.1 Hz to 4 GHz with precisely controlled pulse edges.

If full automation is not immediately required, the 9500C can be configured with just a few, or even one, active head. Additional heads can be easily added as needs change. To request a price quote, use the link to the product page below.

LoRa Corecell full-duplex gateway reference designs from Semtech are tailored to address applications operating in the U.S. 915-MHz and China 490-MHz ISM bands. Both the SX1302CFD915W1-H (915-MHz) and SX1302CFD490GW1 (490-MHz) reference designs leverage Semtech’s LoRa Core SX1302 digital baseband IC and SX1255/7 RF transceiver.

The reference design files are available to download from the Semtech website. While evaluation kits are not offered for purchase, the hardware used in the design comprises a Corecell board populated with the LoRa Core chips, a duplexer, and a Raspberry Pi. The design supports full-duplex operation with eight uplink channels and one downlink channel.

Using the capabilities of the SX1302 baseband IC, the uplink channels can detect up to 64 LoRa packets and simultaneously demodulate 16 125-kHz LoRa packets with spreading factors between SF5 and SF12. The SX1302 also provides one 125/250/500-kHz demodulator for single SF operation and one (G)FSK demodulator for legacy applications.

The gateway implementation achieves a tenfold reduction in power compared to the previous generation of LoRa baseband ICs. With a discrete power amplifier and low-noise amplifier, transmit output power at the antenna port can be up to +27 dBm. Receive sensitivity can be as low as -140.8 dBm for the U.S. 915-MHz band and -137.4 dBm for the China 490-MHz band.
