Launch of New Encryption Companion Device
Provides a simplified automotive network security path
Reduce costs and time to market


With the increase in in-vehicle network connectivity such as Bluetooth and LTE/5G, the need for new cybersecurity regulations and specifications is emerging.

Microchip Technology has launched the CryptoAutomotive security IC TrustAnchor100 (hereinafter TA100), which enables OEMs and module suppliers to meet security requirements and upgrade existing designs more simply.

The encryption companion device supports in-vehicle network security solutions, such as secure boot, firmware updates, and message authentication, including a bus-speed CAN (Controller Area Network) MAC.

The TA100 provides an in-vehicle alternative network architecture for secure boot and message authentication. This feature set was designed under close review of several key OEM cybersecurity specifications to facilitate the promotion of OEM PPAP (Part Production Approval) by Tier 1 suppliers.

In addition, Microchip provides security requirements and RFQ (Request for Quote) review services to help Tier 1 suppliers develop trained responses and increase their project winning success rate.

TA100 reduces risk, cost, and time-to-market by eliminating issues related to secure code development and deployment through the provisioning of pre-programmed cryptographic internal application code with unique asymmetric key pairs and associated x.509 certificates.

In addition, the device has been verified to have high resistance to attacks through intensive third-party vulnerability assessments. It has obtained Automotive AEC-Q100 Grade-1 certification, FIPS 140-2 CMVP Security Level 2 and Physical Key Protection Level 3 certifications, and achieved the highest vulnerability assessment rating from JIL High.

Nuri Dagdeviren, Vice President of Security Products, said, “TrustAnchor100 is mass-producible for customers by combining it with the TA100 and an integrated software stack,” adding, “By providing the software, it will be possible to easily add security to any automotive module.”
