Abstract
A microprocessor includes a cryptographic engine, M buffer units, and a controller. The cryptographic engine is configured to execute cryptographic algorithms. The M buffer units are configured to cache data required by an access request of a corresponding execution environment. M is an integer greater than or equal to 1. The controller is connected to the cryptographic engine and the M buffer units. The controller is configured to receive the access request from a first execution environment and instruct the cryptographic engine to execute the cryptographic algorithm requested by the access request using the required data cached by the buffer unit corresponding to the first execution environment from which the access request comes. The access request is used to access the cryptographic engine to execute a cryptographic algorithm. The first execution environment is one execution environment among N execution environments. N is an integer greater than or equal to 1.
