Abstract： In Attribute-Based Access Control (ABAC) , how to respond quickly to the retrieved access control request is very important, and it is undoubtedly time-consuming to traverse all attribute values in each rule of the policy set until finding the appropriate rule. Therefore, the paper proposes an ABAC retrieval method based on binary sequence, and uses binary identification and binary coding to represent attribute based access control policies and access control requests. Through the logical operation of binary identification, select the appropriate group. In the group, find the appropriate rules by matching the binary code of access control request with the binary code of all rules, reduce the process of matching the attributes of rules in the policy set with the attributes of access control request, and improve the efficiency of policy retrieval. In the experiment, this paper compares the efficiency of similar retrieval methods from three aspects: strategy preprocessing, strategy evaluation time and total strategy retrieval time. The results show that the strategy retrieval method proposed in this paper has higher retrieval efficiency.
