Research on Microservice Access Control Model Based on Behavior Information in B5G Scenario

With the development of mobile communication networks, the trend of microservices in core networks is becoming more and more obvious. The open and distributed characteristics make it face serious security problems, such as unauthorized access and malicious intrusion. Aim at the above-mentioned problems, this paper proposes a behavioral information-based microservice access control model in the B5G scenario. Then, the article introduces in detail the state evaluation algorithm based on behavior chain and the dynamic evaluation algorithm based on fuzzy analytic hierarchy process (FAHP) in the access control model. Finally, the effectiveness of the access control model proposed in this paper is verified by a comparative experiment with the current authentication scheme. The experimental results show that the access control model proposed in this paper is more resistant to diverse attacks and more adaptable to complex microservice environments.
