I²C Low-Voltage SHA-3 Authenticator

Protect Your Development Investment with Crypto-Strong Authentication and Advanced Physical Security

Product Details

The DS28C16 secure authenticator combines FIPS202-compliant Secure Hash Algorithm (SHA-3) challenge and response authentication with secured EEPROM.

The device provides a core set of cryptographic tools derived from integrated blocks including a SHA-3 engine, 256 bits of secured user EEPROM, a decrement-only counter and a unique 64-bit ROM identification number (ROM ID). The unique ROM ID is used as a fundamental input parameter for cryptographic operations and serves as an electronic serial number within the application.

Key Features

  • Robust Countermeasures Protect Against Security Attacks
    • All Stored Data Cryptographically Protected from Discovery
  • Efficient Secure Hash Algorithm Authenticates Peripherals
    • FIPS 202-Compliant SHA-3 Algorithm for Challenge/Response Authentication
    • FIPS 198-Compliant Keyed-Hash Message Authentication Code (HMAC)
  • Supplemental Features Enable Easy Integration into End Applications
    • 17-Bit One-Time Settable, Nonvolatile Decrement-Only Counter with Authenticated Read
    • Secure Storage for Secrets
    • 256 Bits of Secure EEPROM for User Data
    • Unique and Unalterable Factory Programmed 64-Bit Identification Number (ROM ID)
    • I²C Communications Up to 1MHz
    • Operating Range: 1.62V–3.63V, -40°C to +85°C
