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.

Applications

• Accessory and Peripheral Secure Authentication
• Battery Authentication and Charge Cycle Tracking
• Medical Tools/Accessories Authentication and Calibration
