Research on Resource Trust Access Control Based on Cloud Computing Environment

In this paper, a method of access control based on resource trust is proposed to solve the problem of trust access between cloud users and cloud resources. This method introduces trust into the attribute access control model in cloud environment, and proposes an optimization technology of attribute access control based on trust evaluation in cloud computing environment. By introducing the evaluation credibility, entity familiarity and evaluation similarity, the trust degree is calculated through this method, and the comprehensive trust degree of users or resources is achieved through direct trust, indirect trust and recommendation trust, so as to achieve the purpose of improving the security of attribute access control.
