RESOURCE ACCESS METHOD AND DEVICE

摘要

The present invention relates to the field of communication, and provided are a resource access method and device in machine-to-machine communications (M2M). The resource access method in M2M comprises: receiving an access request of a requester resource to access the resource to be accessed, the access request containing: an identifier of the resource to be accessed, a requester resource identifier (RI), and an operation of the request to the resource to be accessed; determining the resource to be accessed according to the identifier of the resource to be accessed; obtaining an access control policy resource of the resource to be accessed; determining that the requester resource is a group member of the group resource corresponding to the group resource identifier having an operation authority of the requested operation in the access control policy resource; and performing the requested operation for the resource to be accessed. By determining whether the requester resource is a group member of a group resource having the operation authority, the present invention achieves access control based on the group.
