Abstract
Various embodiments are directed to a system for accessing a self-encrypting drive (SED) based on a blind challenge authentication response mechanism (BCRAM). An SED may be authenticated within a system, for example, upon resuming from a sleep state, based on a challenge generated within the SED, signed using a private key by a trusted execution environment (TEE) and authenticated using a corresponding public key within the SED.
