Whenever I visit Silicon Valley, I feel a sense of being part of something. My wife always tells me I am happier in Silicon Valley than I am at home.

Random number generator software targets IoT devices

Intrinsic ID announced Zign RNG, a new offering enabling IoT chip providers and device makers to establish a high-security random number generator in software enabling it to be deployed on devices even after silicon fabrication to ensure a true source of randomness for IoT devices.

Random number generators (RNGs) are essential for cryptographic applications and form the foundation of security systems. For IoT devices, an RNG is generally implemented by incorporating hardware peripheral controllers, which are proving to be imperfect as a source for real randomness because they start with a deterministic input. A report from Bishop Fox shows critical vulnerabilities have been disclosed in hardware random number generators used in billions of Internet of Things (IoT) devices whereby it fails to properly generate random numbers, thus undermining their security and putting them at risk of attacks.

Design and verification of automotive SoCs that utilize the emerging CAN XL and TSN Ethernet 1/10G networking and control protocols integrate CAST’s validated design IP for both standards with Avery’s verification IP (VIP) that streamlines the design and verification process to an ensure higher quality designs as well as compliance with the standards. The new solutions include the CAN XL and TSN Ethernet design IP from CAST and the corresponding VIP from Avery, which is one of the most comprehensive verification suites available.

CAN XL is the third generation of the CAN data link layer that enables net data rates of up to 10 Mbit/sec averyand supports an extra-large (XL) payload of up to 2048 bytes. High-speed Ethernet in automotive supports the need for multiple streams of data from cameras, sensors, and radars to be transferred and processed in real time. Time Sensitive Networking (TSN) addresses the scheduling, low-latency, and safety requirements of mission-critical control systems like braking, steering, ADAS and other functions.

The expanded partnership builds on the companies’ thirteen-year-long relationship and creates best-in-class, robust, pre-validated CAN FD/XL and TSN Ethernet MAC solutions, streamlining the design and verification process for mutual customers. Avery’s virtual prototype solution for CAN XL and TSN Ethernet enables running CAST’s CAN XL IP and TSN Ethernet MAC reference designs and software stack in a QEMU/SystemVerilog co-simulation solution running on RTOS and supports RISC-V, Arm, and Microblaze embedded processor solutions.

“As an increasing amount of data gets moved throughout and around the connected automobile chip developers need the latest high-bandwidth and high-speed connectivity solutions enabled by evolving networking standards. CAST has a long track record of providing reliable and accurate IP solutions to incorporate the latest automotive networking functionality in SoCs, and this expands our established partnership to deliver high quality VIP to further accelerate the verification of these designs. We look forward to continuing our collaboration to address the current and next-generation protocols being used in a rapidly evolving automotive electronics market,” said Chris Browy vice president of sales and marketing at Avery.
