摘要：Cloud computing is one of the emerging technologies. The cloud environment is a large open distributed system. It is important to preserve the data, as well as, privacy of users. Access Control methods ensure that authorized user's access the data and the system. Current Role Based Access Control architecture has a lot of drawbacks which can be minimized by this proposed architecture. This paper presents a new extended architecture of RBAC which can resolve the security issues and data loss issues by using restriction policy on number of roles, number of users per role and number of transaction per day/hour/user. At the end this work is compared with the previous one and shows that this new advance architecture helps to improve the level of security.
