Security attribute-based access control formalized verification method for ARM (Advanced RISC Machines) architecture

The invention discloses a security attribute-based access control formalized verification method for an ARM (Advanced RISC Machines) architecture, which abstracts entities in a system and endows the entities with security attributes so as to realize flexible and fine-grained system resource management and enhance resource security protection of the ARM architecture. The method comprises the following steps: firstly, defining atomic security attributes of system resources, and assigning security attributes for entities in a system based on the atomic security attributes; secondly, an access control strategy is defined, the access control strategy is used for judging whether access is allowed or not for resource access requests generated in the trusted execution environment and the non-trusted execution environment, and subject attributes, object attributes and access attributes are configured as input and the like; according to the method, the fine-grained description of the memory read-write permission of the
