A Secure Multi-Party Authentication Model for High-Frequency Cross-Domain Access
Most of the existing cross-domain authentication methods rely on the decentralized mechanism of identity providers to ensure the reliability of authentication credentials,but there is still insufficient security protection caused by centralized authentication services.To solve the authentication security problem in high-frequency cross-domain access,a multi-party authentication model is proposed.This model draws on the idea of distributed consensus and realizes the multi-party communication and joint authentication among authentication nodes through the safe and practical Byzantine fault-tolerant mechanism.Meanwhile,based on the authentication results,it can locate and replace the risk authentication nodes in real time,reorganize the authentication network and enhance the flexibility of the system.Simulation experiments tested the attack resistance and service quality of the model.The results show that when the proportion of risk authentication nodes does not exceed 33％ ,the authentication results are still safe and reliable;the authentication time overhead increases slowly with the expansion of node scale and has a certain degree of real-time performance under a reasonable node size,which is suitable for high-frequency cross-domain scenarios.In addition,the network reorganization mechanism can operate independently,the time overhead is controllable and the system robustness is good.
