Winbond partners with Karamba to provide secure memory solution

1 min read

Winbond Electronics, a global supplier of semiconductor memory solutions, and Karamba Security, an embedded security provider for connected devices, have collaborated in the development of an automotive cybersecurity solution.

Karamba’s XGuard software is already used in the automotive and IoT markets, and enables customers to comply with the new UN R155 regulation, detect and prevent cyber-attacks on devices and do so without changing R&D and validation processes.

Winbond’s TrustME W77Q expands flash memory capacity to 128Mb, while maintaining its hardware root-of-trust and secure, encrypted, data-storage and data-transfer capabilities.

The combined Winbond-Karamba solution now takes cybersecurity protection several steps further by maintaining system integrity even if the ECU itself is breached. Supported by Winbond’s W77Q secure channel, and Karamba’s XGuard whitelist verification and CFI (Control Flow Integrity) validation, users will be able to benefit from an out-of-the-box secured OTA updates, without having to invest resources in costly OTA secure channels.

The combined solution offers deterministic integrity checks, from development throughout the supply chain, starting from the silicon Fab, through deployment in the customers’ manufacturing plant, to runtime, without requiring customers to change their development or manufacturing processes.

"We are excited to be working with Winbond to provide an out-of-the-box secure memory solution for our automotive and IoT customers," said Assaf Harel, Karamba's Chief Scientist and Co-Founder. "The Winbond W77Q Secure Memory adds an additional layer of security to the Karamba's XGuard", he added, "enabling secure Over-The-Air update, allowing automotive customers to meet the UN R155 & R156 and the ISO21434 new security regulations—now mandated by many of our customers—without having to make costly changes to R&D or supply chain processes."
