Atmel says its latest CryptoAuthentication product – the ATECC508A – is the first to integrate the Elliptic Curve Diffie–Hellman (ECDH) security protocol, an ultra secure method to provide key agreement for encryption/decryption. The part, which also features Elliptic Curve Digital Signature Algorithm (ECDSA) authentication, is targeted at IoT applications.
The ATECC508A is the second device in Atmel's CryptoAuthentication portfolio to offer advanced Elliptic Curve Cryptography (ECC) capabilities. It is compatible with any MCU or MPU and requires only a single general purpose I/O over a wide voltage range.
Rob Valiton, general manager of Atmel's Automotive, Aerospace and Memory business units, said: "It is the first device of its kind to apply hardware based key storage to provide the full complement of security capabilities; specifically confidentiality, data integrity and authentication. We are excited to continue bringing ultra secure crypto element solutions to a wide range of applications."
With a guaranteed 72bit unique ID, the device includes a 10.5kbit EEPROM for secret and private keys and is available in UDFN, SOIC, and three lead contact packages.
