Access control method and device, computer equipment and storage medium

The invention relates to an access control method and device, computer equipment and a storage medium, and the method comprises the steps: receiving an access request of an access initiating object for an access target object, and obtaining a first access identification uniquely corresponding to the access initiating object and the access target object; determining a target memory space from a plurality of memory spaces of a local shared memory according to the first access identifier; and obtaining access restriction information contained in a data structure corresponding to the target memoryspace, and determining whether to allow the access initiating object to access the access target object or not according to the access restriction information, thus when an access request is received, the corresponding access restriction information is directly acquired from the local shared memory according to the access identifier, so that the access token is prevented from being acquired fromother equipment through a
