DeepCover embedded security solutions protect sensitive data with multiple layers of advanced physical security and provide highly secure storage of the authentication secret keys. Using the FIPS 180 based SHA-256 authentication algorithm, the DS28C22 combines crypto-strong, bidirectional, secure challenge-and-response authentication with small message encryption.
Through bidirectional authentication, the host and the peripheral authenticate one another, protecting the IP in the peripheral from a non-authentic host trying to modify operation of the peripheral. A bidirectional security model enables two-way authentication and encryption between a host system and slave-embedded DS28C22. Strong die-level protection securely stores the authentication.
An optiona lDS28C22 pre-programming service prevents supply chain venders from compromising a solution and ensures no exposure of cryptographic keys. The device also includes a dedicated hardware accelerated engine for SHA computations.
