EVALUATION KIT AVAILABLE Request Security User Guide and Developer Software › Deep Cover Radiation Resistant 1-Wire Authenticator General Description The DS28E83 is a radiation-resistant 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-patible true random number genera­tor (TRNG), 10Kb of secured OTP, one 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 and include FIPS 186-pliant ECDSA signature generation and verification to support a bidirectional asymmetric key authentication model. The SHA-256 secret key capabilities are pli­ant with FIPS 180 and are flexibly used either in conjunc­tion with ECDSA operations or independently for multiple HMAC functions. The GPIO pin can be operated under mand control and include configurability supporting authenticated and nonauthenticated operation, including an ECDSA-based cryptorobust mode to support secure boot of a host processor. Deep Cover® 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 active die shield, encrypted storage of keys, and algorithmic methods.
