    摘要: Systems and techniques for performing cryptographic operations based on public key validity registers are described. A described system includes a controller and a memory structure to store one or more public keys. The memory structure includes one or more validity registers that respectively correspond to the one or more public keys. The controller has exclusive write access to the validity register. The controller can be configured to perform an authentication of a public key, write an authentication status value to the corresponding validity register based on a result of the authentication, and perform one or more cryptographic operations using the public key that are conditional on the validity register indicating an authenticated status for the public key.
