Product Overview

The DS28E83 is a radiation-resistant secure authenticator that provides a core set of cryptographic tools derived from integrated asymmetric (ECC-P256) and symmetric (SHA-256) security functions. In addition to the security services provided by the hardware implemented crypto engines, the device integrates a FIPS-compatible true random number generator (TRNG), 10Kb of secured OTP, one configurable GPIO, and a unique 64-bit ROM identification number (ROM ID). The ECC public/private key capabilities operate from the NIST defined P-256 curve and include FIPS 186-compliant ECDSA signature generation and verification to support a bidirectional asymmetric key authentication model. The SHA-256 secret key capabilities are compliant with FIPS 180 and are flexibly used either in conjunction with ECDSA operations or independently for multiple HMAC functions.
  • Accessory and Peripheral Secure Authentication; Medical Consumables Secure Authentication; Medical Tools/Accessories Identification and Calibration;
  • Secure Boot or Download of Firmware and/or System Parameters; Secure Storage of Cryptographic Keys for Host Controllers
  • SHA-256 compute engine
  • SHA-256 OTP (One-Time Pad) encrypted R/W of configurable memory through ECDH Established Key
  • One GPIO Pin with optional authentication control
  • TRNG with NIST SP 800-90B compliant entropy source with function to read out
  • Optional chip generated Pr/Pu key pairs for ECC operations or secrets for SHA256 functions
  • Unique and unalterable factory programmed 64-Bit identification number (ROM ID)
  • Advanced 1-Wire protocol minimizes interface to just single contact
