DS28E25P Memory IC Chip DeepCover Secure Authenticator With 1-Wire SHA-256 And 4Kb User EEPROM
Product Description Of DS28E25P
DeepCover™ embedded security solutions cloak sensitive data under multiple layers of advanced physical security to provide the most secure key storage possible.
The DeepCover Secure Authenticator DS28E25P combines crypto-strong, bidirectional, secure challengeand- response authentication functionality with an implementation based on the FIPS 180-3-specified Secure Hash Algorithm (SHA-256). A 4Kb user-programmable EEPROM array provides nonvolatile storage of application data and additional protected memory holds a readprotected secret for SHA-256 operations and settings for user memory control.
