A Framework for Encryption and Authentication Cryptosystem (EAC) for Shared Cloud Storage

Abstract

The cryptosystem provides a secure way to share files among other users without worrying about the size or number of files and the leakage of data in between of transit that underpins the adaptable assignment of reduced rights for users and data. The key-size for encryption or decryption is autonomous of the number of data or files such that the cost of our plot is steady no matter how habitually clients transfer records to the cloud server. In expansion, the verification prepare in our plot tackles the leakage issue of information sharing. The cloud server gets the token of download-applicant and after that controls download right. This paper proposes a framework by which the data can be shared with users seamlessly without worrying about security. To realize proficient and secure information sharing in energetic cloud capacity, the proposed strategy ought to be steady in cost, and ought to be leakage-resilient.
