Abstract: A resource management method suitable for a security architecture system including a secure element subsystem. The security architecture system is configured with N chip lifecycle states, N being an integer greater than 1, the secure element subsystem stores a plurality of resources, an access authority of the resources being associated with the N chip lifecycle states. The method includes performing access control on a resource based on a current chip lifecycle state of the security architecture system, the current chip lifecycle state of the security architecture system belonging to one of the N chip lifecycle states.

Abstract: A microprocessor comprising a cryptographic engine and a controller. The controller is connected to the cryptographic engine and configured to receive a plurality of access requests from a plurality of execution environments, respectively and respond to one of the plurality of access requests and instruct the cryptographic engine to execute a cryptographic algorithm.

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.

Abstract: 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.
