Research on Cloud Security Model Based on Trusted Third Party on Multi-tenant Environment

Aiming at multi-tenant environments for cloud computing,introducing the trusted third party is into cloud security solutions,this paper proposed a new cloud security model based on trusted third party.Then we designed the authentication protocol and a multi-tenant resource allocation algorithm based on TTP.Finally,the CloudSim simulation tools were used for simulation and performance analysis,and Short Jobs First strategy,First-come First-served policy were compared with TTP strategy in successful implementation rate of resources.The experimental results show that the model provides the highest credibility cloud node resources to cloud users,builds a trust web between entities effectively,verifies the correctness of the data and the correctness of the data exchange,and provides a multi-level,end-toend security services in the distributed environment.
