AN ENCRYPTION SCHEME WITH SUPPORTABLE ALLOCATION IN CLOUD COMPUTING

Within the computing atmosphere, cloud servers can have many data services, for example remote data storage furthermore to outsourced delegation computation. For data storage, servers store up numerous volume of shared information, which may be utilized by way of authoritative users. Within our work we offer anti-collusion circuit cipher text based file encryption process because cipher text based file encryption process is conceptually faster to established means of access control. We try to improve the cipher text based file encryption methods by verifiable delegation in cloud system to think about data privacy, fine-grained data access control furthermore to verifiability of delegation. In hybrid representation of verifiable delegation cipher text-policy based file encryption, a circuit cipher text-policy based file encryption, a symmetric file encryption system with an secure-then-mac mechanism are functional to make certain privacy, fine-grained access control furthermore to verifiable delegation
