A microprocessor includes a cryptographic engine and a controller. The cryptographic engine is configured to execute a cryptographic algorithm. The controller is connected to the cryptographic engine. The controller is configured to receive an access request from a first execution environment. The access request accesses the cryptographic engine to execute the cryptographic algorithm. The access request includes at least identification information. The identification information indicates that the access request is from the first execution environment. The first execution environment is an execution environment of a number N execution environments. N is an integer greater than or equal to 1. The controller is further configured to, based on the identification information, instruct the cryptographic engine to execute the cryptographic algorithm that needs to be executed required by the access request.
