Jasleen Saini, Roshan Srivastava

Abstract: Cloud Computing provides the best platform for such a sharing service because of its scalability and availability. Cipher text policy attribute-based is becoming an appreciative to guarantee data security in cloud computing. In this paper, key escrow problem is solved by using the scheme of homomorphic encryption in which mathematical operations are done on encrypted data without compromising the encryption and proxy re-encryption is also used which is master secret secure. Also Diffie Hellman algorithm is used to make the data more secure. In this paper, previous related work is reviewed with a concentration on the security challenges associated with sharing of data in which third party is involved.

Keywords: Homomorphic Encryption, Diffie Hellman Algorithm, Proxy Re-Encryption, Key Escrow
