The cloud is vulnerable to privacy and security attacks which might be a primary difficulty to its wholesome reputation because the primary means of statistics sharing in these day′s world. We describe new public-key cryptosystems which produce regular-size ciphertexts such that green delegation of decryption rights for any set of ciphertexts are viable. The novelty is that you′ll combination any set of mystery keys and lead them to as compact as a single key, however encompassing the strength of all of the keys being aggregated. However, the traditional Key-Aggregation Cryptosystems (KAC) does no longer have any formal proofs. In this paper, we proposed Chosen Plaintext Attack (CPA) and Chosen Ciphertext Attack (CCA) comfortable KAC structures that are successfully implementable using elliptic curves and are appropriate for implementation on cloud primarily based statistics sharing environments.
