By introducing key sizes associated with 256 bits of security strength, the TA101 offers great key strength diversity now and for future applications. ~Microchip.
Microchip Technology has launched its new Trust Anchor security integrated chip (IC), the TA101. The device supports large key sizes, including ECC P521, SHA512, RSA-4K, and AES256, offering enhanced security. It also provides future scalability while maintaining backward compatibility with smaller keys.
It is AEC-Q100 Grade 1 qualified and available as an industrial-grade crypto-authentication security IC as-well-as a crypto-automotive security IC. It complies with government and automotive original equipment manufacturers (OEM) cybersecurity requirements, which are now incorporating larger key sizes and the Edwards curve ed25519 algorithm standards. The TA101 is suitable for automotive security, data center, and industrial applications.
The security chip works with microcontrollers (MCUs) or microprocessors (MPUs) to manage cryptographic functions such as public key infrastructure, certificate management, and secure key storage. It enables easy patch updates, message authentication, transport layer security (TLS), secure boot, high-bandwidth digital content protection (HDCP), firmware updates, security upgrades, transfer of ownership, key management, and WPC Qi 1.3 authentication.
The IC offers an external solution for secure boot and message authentication, compatible with a wide range of MCUs/MPUs. It includes the commercial national security algorithm (CNSA) suite 1.0 and the ed25519 curve. Pre-programmed and pre-provisioned in Microchip’s certified facilities, it minimizes secure code development risks.
It is supported by the CryptoAuth Trust Platform development kit and TA101 socket boards with a mikroBUS connector. The socket boards are compatible with the mikroBUS Xplained Pro extension board for SAM MCU designs. The TA101 AUTOSAR Microcontroller Abstraction Layer (MCAL) is ASPICE Level 2 compliant, and Microchip’s crypto-authentication library ensures easy integration into standard operating systems or custom software stacks. The Trust Platform Development Suite (TPDS) aids in prototype configuration and factory provisioning preparation.
