General Description

DeepCover® embedded security solutions cloak sensitive data under multiple layers of advanced physical security to provide the industry’s most secure key storage possible.

The Deepcover Secure Authenticator (DS28EL25) 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.

Key Features

  • Symmetric Key-Based Bidirectional Secure Authentication Model Based on SHA-256.
  • Dedicated Hardware-Accelerated SHA Engine for Generating SHA-256 MACs.
  • Strong Authentication with a High Bit Count, UserProgrammable Secret, and Input Challenge.
  • 4096 Bits of User EEPROM Partitioned Into 16 Pages of 256 Bits.
  • User-Programmable and Irreversible EEPROM Protection Modes Including Authentication, Write and Read Protect, and OTP/EPROM Emulation.
  • Unique, Factory-Programmed 64.
