As vehicles become more connected and technologically advanced, the need for enhanced security measures increases. New government and automotive OEM cybersecurity requirements are beginning to include larger key sizes and the Edwards Curve ed25519 algorithm standard. In response, Microchip Technology has introduced the TA101, which supports large keys up to ECC P521, SHA512, RSA-4K, and AES256, providing a higher security strength that exceeds the current standard and allows room for future adaptation. The TA101 is available as an industrial-grade CryptoAuthentication™ security IC and as a CryptoAutomotive™ security IC supporting AEC-Q100 Level 1 qualified devices.
As the newest device in Microchip's security IC portfolio, the TA101 is designed to support automotive security, data centre 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, transfer, key management and WPC Qi ® 1.3 authentication.
"It is critical for OEMs to not only comply with current standards, but to stay one step ahead of the curve when it comes to security. By introducing key sizes associated with 256-bit security strength, the TA101 provides great key strength diversity for today's and tomorrow's applications," said Nuri Dagdeviren, corporate vice president of Microchip's Secure Computing Group. "In addition, Microchip's modular approach to security solutions allows customers to select the best sized and priced MCU for the module's focused application while standardising on a single security solution that meets virtually all security requirements."
The TA101 provides an alternative architecture for on-chip multi-core MCU/MPU management for in-vehicle networks by providing off-chip components to handle secure boot and message authentication. The device is compatible with a wide range of MCUs or MPUs and supports flexible solutions that help reduce cost and time-to-market.
The TA101 provides the 1.0 algorithmic suite and ed25519 curve required by the Commercial National Security Algorithm (CNSA) in a single IC. It is pre-programmed and pre-configured in Microchip's Common Criteria ALC_DVS.2 certified facility, reducing the risk associated with safety code development and implementation.
Development Tools
The TA101 is supported by the CryptoAuth Trust Platform development kit and multiple TA101 socket boards with mikroBUS™ connectors.These socket boards can also be used with the mikroBUS Xplained Pro Expansion Board, which connects to a variety of Xplained Pro boards to develop designs using SAM MCUs.
The TA101 AUTOSAR ® Microcontroller Abstraction Layer (MCAL) conforms to ASPICE Level 2. Microchip's CryptoAuthentication software library seamlessly integrates into industry-standard operating systems or custom software stacks for cryptographic functionality. trust Platform Development Suite (TPDS) can be used to develop designs using SAM MCUs. The Trust Platform Development Suite (TPDS) can be used to configure prototypes and prepare them for configuration at Microchip's secure factory.
