Microprocessor, data processing method, electronic device, and storage medium

A data processing method implemented by a microprocessor, the microprocessor comprising:

• a cryptographic engine configured to execute cryptographic algorithms;
• M buffer units configured to cache data required by an access request of a corresponding execution environment, M being an integer greater than or equal to 1;
• a controller connected to the cryptographic engine and the M buffer units, the data processing method causing the controller to:
• receive the access request from a first execution environment, the access request being used to access the cryptographic engine to execute a cryptographic algorithm, the first execution environment being one execution environment among N execution environments, N being an integer greater than or equal to 1;
• 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 from.

A non-transitory computer-readable storage medium comprising:

• a plurality of computer program codes that, when being executed by a processor, cause the processor to:
• receive an access request from a first execution environment, the access request being used to access a cryptographic engine to execute a cryptographic algorithm, the first execution environment being one execution environment among N execution environments, N being an integer greater than or equal to 1;
• and
• instruct the cryptographic engine to execute a cryptographic algorithm requested by the access request using required data cached by a buffer unit corresponding to the first execution environment from which the access request comes.
