By Maxim Integrated 235
Maxim's DS28C36Q+U is a secure authenticator that 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 provided by the hardware-implemented crypto engines, the device integrates a FIPS/NIST true random number generator (RNG), 8 Kb of secured EEPROM, a decrement-only counter, two configurable general-purpose input/output (GPIO) pins, and a unique 64-bit ROM identification number (ROM ID).
The ECC public and private key capabilities operate from the NIST-defined, P-256 curve and include FIPS-186-compliant ECDSA signature generation and verification to support a bidirectional, asymmetric key authentication model. The SHA-256's secret-key capabilities are compliant with FIPS 180 and are flexibly used either in conjunction with ECDSA operations or independently for multiple HMAC functions.
Two GPIO pins can be independently operated under command control and include configurability supporting authenticated and non-authenticated operation, including an ECDSA-based, crypto-robust mode to support secure-boot of a host processor.
DeepCover embedded security solutions cloak sensitive data under multiple layers of advanced security to provide the most secure key storage possible. To protect against device-level security attacks, invasive and noninvasive countermeasures are implemented including an active die shield, encrypted storage of keys, and algorithmic methods.
