Analog Devices Inc. DS28C16 DeepCover® SHA-3 I2C Authenticator
Analog Devices Inc. DS28C16 DeepCover® SHA-3 I2C Authenticator provides a core set of cryptographic tools derived from integrated blocks. These integrated blocks include a Secure Hash Algorithm (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.
Features
- Robust countermeasures protect against security attacks, all stored data is cryptographically protected from discovery
- Efficient secure hash algorithm to authenticate peripherals
- FIPS 202-compliant SHA-3 algorithm for challenge/response authentication
- FIPS 198-compliant Keyed-Hash Message Authentication Code (HMAC)
- 62V to 3.63V input voltage range
- -40°C to +85°C operating temperature range
- 8-pin, 2mm x 2mm TDFN-EP package
- 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
Applications
- Medical tools/accessories authentication and calibration
- Accessory and peripheral secure authentication
- Battery authentication and charge cycle tracking
