Article Details
The ATECC608A - MAHDA - S from Microchip Technology is a sophisticated crypto authentication device designed to meet the stringent security requirements of modern electronic systems.
1. Key Features
Robust Cryptographic Support
ECDSA and ECDH Capabilities: It integrates the Elliptic Curve Digital Signature Algorithm (ECDSA) and Elliptic Curve Diffie - Hellman (ECDH) protocols. ECDSA enables secure digital signatures for verifying the authenticity of data and messages, while ECDH facilitates secure key exchange, ensuring that communication channels are encrypted and secure.
NIST Standard P256 Support: The device supports the NIST standard P256 elliptic curve, which is widely recognized for its high security and efficiency in cryptographic operations. This allows for reliable and standardized security in various applications.
Secure Key and Data Storage
Protected Storage: It can store up to 16 keys, certificates, or data elements. This provides a secure repository for sensitive information, safeguarding it from unauthorized access and tampering. The guaranteed unique 72 - bit serial number per chip adds an extra layer of security and can be used for device identification and anti - counterfeiting.
Versatile Crypto Operations Support
Hash and Encryption Functions: The ATECC608A - MAHDA - S offers SHA - 256 and HMAC hash functions, including off - chip context save/restore. It also supports AES - 128 encryption and decryption, along with Galois field multiply for GCM. This combination of hash and encryption capabilities enables comprehensive data protection and integrity checks.
TLS Support: It provides turnkey PRF/HKDF calculation for TLS 1.2 and 1.3, facilitating secure communication over the Internet and ensuring that data transmitted between devices and servers remains confidential and unaltered.
Dual High - Endurance Monotonic Counter
The chip is equipped with 2 high - endurance monotonic counters. These can be used for various purposes such as tracking events, managing access control, or implementing time - based security mechanisms.
