CAST introduces the First CANsec IP Core for CAN XL Bus Safety

{Hardware} acceleration engine for the brand new CANsec specification provides knowledge authenticity and confidentiality to any CAN XL bus system

Woodcliff Lake, New Jersey — September 13, 2022 — Semiconductor mental property supplier CAST in the present day introduced the speedy availability of an IP core that implements CANsec security measures to raised defend any CAN XL bus.

The CAN protocol defines an information transmission bus that’s extraordinarily common in automotive and industrial techniques. Originating within the Eighties, nonetheless, it lacks any built-in knowledge safety, making CAN bus techniques weak to cyberattacks and different threats.

The most recent model of the CAN protocol, CAN XL, will increase transmission velocity and provides knowledge size scalability. The brand new CANsec protocol — being developed by CAN in Automation (CiA) as draft specification 613-1 and -2 — takes benefit of those CAN XL options so as to add a layer of safety.

The brand new CAN-SEC CANsec Acceleration Engine IP core works with the CAN XL core out there from CAST or some other CAN XL standard-conforming controller IP core. It protects the CAN XL knowledge payload utilizing two NIST-approved ciphers with as much as 256-bit key lengths:

  • AES-CMAC protects knowledge integrity and authenticity, and
  • AES-GCM moreover protects confidentiality.

The core protects a number of nodes or units on the identical CAN XL bus utilizing as much as 256 safe channels to speak with the CAN XL controller and the system’s host processor.

Implementing CANsec in {hardware} quite than software program, the CAN-SEC Core provides negligible delay to knowledge on the CAN XL bus whereas defending that knowledge from recognized cyber-attacks together with spoofing, sniffing and replay, repudiation, and useful resource exhaustion.

The CANsec core developed by Fraunhofer IPMS was rigorously verified and produced to fulfill CAST’s IP reusability and high quality requirements and has been publicly utilized in a demonstrator from Renesas Electronics Company. It’s out there now from CAST.

“As with CAN in 2002, TSN Ethernet in 2017, and CAN XL in 2020, the superior analysis and growth workforce at Fraunhofer IPMS has enabled us to offer one of many first out there IP cores for a hugely-beneficial new expertise,” mentioned Nikos Zervas, chief government officer at CAST. “CAN XL helps reply the demanding will increase in automotive system complexity, and now CANsec helps defend drivers and passengers from the rising risk of digital assault.”
