The Optimization Mechanism Research of Distributed Unified Authentication Based on Cache

摘要

It is one of the popular and effective way to build a unified authentication center to implement single sign-on among many applications in the enterprise. How to deal with the high concurrent and high flow of user requests to ensure the stability and efficiency of the authentication service is most important when integrating multiple systems. Aiming at the problem of authentication center, such as overloaded, single point of failure, slow response time, etc. we put forward a distributed architecture with cache to enable the unified authentication. The authentication tickets can be shared among multiple nodes by cache. The hot and important data can be prefetched to cache to improve the response time. A multi-factor cache replacement algorithm based on Hybird is also proposed which combining complex and diverse user behavior to improve the effectiveness of data replacement. The experimental results show that the optimized distributed authentication architecture can guarantee the stability of the system, and the cache mechanism can improve the response time, and a multi factor cache replacement algorithm based on Hybird can improve the cache hit ratio.
