Datakey Datakey CryptoAuthentication™ Memory Token IAT10.5Kb

The IAT10.5Kb CryptoAuthentication ™ memory token utilizes Microchip’s ATECC608A CryptoAuthentication ™ IC, enabling embedded applications, like: • Secure storage/transfer of keys, certificates, passwords • Secure credential with unique, read-only serial number • Crypto Ignition Key (CIK) • Device authentication (anti-counterfeit) with countdown limit use • Secure Boot and Secure Download Firmware Update The token’s internal IC contains a 1208-byte (9664-bit) Data Zone of EEPROM memory that is divided into 16 slots. 8 slots are 36-bytes (288 bits), 7 slots are 72 bytes (576 bits) and one slot is 416 bytes (3328 bits). Each slot can be configured for read-only or read/write access in either clear or encrypted modes. There is also a 64-byte One Time Programmable (OTP) Zone. Data may be written until the zone is locked. Two monotonic counters can be used for limit-use applications. The IC also includes a unique 9-byte (72-bit) non-changeable serial number. The ATECC608A also features a random number generator, hardware support for asymmetric Elliptic Curve Cryptography (ECDH and ECDSACC) and hardware support for symmetric algorithms SHA-256 and AES-128. The IC also incorporates security features to detect tampering and thwart attacks.
