Analog Devices / Maxim Integrated DS28C36 Deep Cover® Secure Authenticator
Analog Devices DS28C36 Deep Cover® Secure Authenticator provides a core set of cryptographic tools derived from integrated asymmetric (ECC-P256) and symmetric (SHA-256) security functions. In addition to the security services offered by the hardware-implemented crypto engines, the Analog Devices DS28C36 integrates a FIPS/NIST true random number generator (RNG). The device also integrates 8Kb of secured EEPROM, a decrement-only counter, two pins of configurable GPIO, and a unique 64-bit ROM identification number (ROM ID). The ECC public/private key capabilities operate from the NIST-defined P-256 curve, including FIPS 186 compliant ECDSA signature generation and verification to support a bidirectional asymmetric key authentication model. The SHA-256 secret-key capabilities comply with FIPS 180 and are flexibly used in conjunction with ECDSA operations or independently for multiple HMAC functions.
The Analog Devices DS28C36 Deep Cover Secure Authenticator is offered in a TDFN-6 package with an exposed pad for superior thermal performance.
