Chip security modules and security encryption methods

Abstract

This invention discloses a chip security module and a security encryption method. By monitoring the executed encryption operation instructions and determining whether the execution process of the encryption operation instructions matches the corresponding security sequence, if the execution process of the encryption operation instructions matches the corresponding security sequence, the current encryption operation instruction outputs the execution result. If the execution process of the encryption operation instructions does not match the corresponding security sequence, corresponding processing actions are taken according to the actual application requirements. The security sequence is used to represent the preset execution process of the corresponding encryption operation instruction. Thus, this invention can improve chip security. Furthermore, since this invention performs monitoring at the software level, different security sequences can be configured to meet different application requirements, while reducing chip design costs.
