Comparitive study on existing and proposed system of access control with anonymous authentication of DA TA stored

摘要

We are proposing a comparative study on new decentralized access control system using ABE algorithm that is going to secure the data that is stored in clouds. This paper compares the existing work and the work which we have proposed. Our system reduces the time limit compared to the existing one. It has good accuracy. Data sent will upload into the cloud very faster. It is a robust system and it informs admin in the case of user revocation. Replay attack is also avoided in which it was not there in the existing system.
