DeepCover Secure Authenticator for Peripheral Authentication

ECDSA cryptography,1-Wire® simplicity, and die-level protections—all in a single chip

Key Benefits
Public-key cryptography simplifies implementation
  • Eliminates the need for host-side key storage
  • Avoids the difficulties of key distribution faced in multislave environments
1-Wire interface reduces interconnect complexity
  • Allows operation from a single dedicated contact
High integration reduces cost and complexity
  • ECDSA engine with 1-Wire interface
  • Nonvolatile (NV) memory
  • Hardware random-number generator
  • Tamper protection circuitry
