Chip security module and security encryption method

Abstract

A chip security module can include: an encryption unit configured to execute an encryption operation instruction, monitor execution process of the encryption operation instruction, and determine whether the execution process of the encryption operation instruction matches a corresponding security sequence; where in response to determining that the execution process of the encryption operation instruction matches the corresponding security sequence, the chip security module controls an execution result being outputted based on the encryption operation instruction; where in response to determining that the execution process of the encryption operation instruction does not match the corresponding security sequence, a corresponding action is taken according to application requirements; and where the security sequence is used for characterizing a preset execution process of the corresponding encryption operation instruction.

Dependencies are inferred from the claim text.
