Microchip releases latest TrustAnchor safety IC to fully meet higher automotive safety certification requirements

【Lansheng Technology News】As cars become more connected and technologically advanced, the need for enhanced safety measures increases. The latest cybersecurity specifications from governments and automotive OEMs are beginning to include larger key sizes and the Edwards Curve ED25519 algorithm standard. To this end, Microchip Technology Inc. recently launched the latest trust anchor security ICTA101, which can meet complex automotive and embedded security use cases. TA101 supports large keys up to ECC P521, SHA512, RSA-4K and AES256, delivering higher security strength than current standards and leaving room for future adjustments while maintaining backward compatibility for smaller keys . TA101 provides CryptoAuthentication™ industrial-grade security IC and CryptoAutomotive™ security IC, supporting devices that meet AEC-Q100 Level 1 standards.

As the latest device in Microchip's security IC portfolio, the TA101 is designed to support automotive security, data center and industrial applications. The cryptographic companion device works with a microcontroller (MCU) or microprocessor (MPU) to handle cryptographic functions including public key infrastructure, certificate management and secure key storage requirements. TA101 provides easy patch updates, message verification, Transport Layer Security (TLS), secure boot, High-bandwidth Digital Content Protection (HDCP), firmware updates, security upgrades, ownership transfer, key management and WPC Qi® 1.3 authentication.

By providing off-chip components to handle secure boot and message verification, TA101 provides an alternative architecture for on-chip multi-core MCU/MPU management of in-vehicle networks. The device is compatible with a variety of MCUs or MPUs, providing a flexible solution that helps reduce costs and time to market.

The TA101 provides the U.S. Commercial National Security Algorithm (CNSA) required 1.0 algorithm suite and the ed25519 curve algorithm in a single IC. The TA101 is pre-programmed and pre-configured in Microchip Common Criteria ALC_DVS.2 certified facilities, reducing the risks associated with secure code development and implementation.
