        abstract = {This paper, proposes a revocable multi-authority CP-ABE scheme, where an efficient and securer evocation method is proposed to solve the attribute revocation problem in the system. the attribute revocation method is efficient in the sense that it incurs less communication cost and computation cost and is secure in the sense that it can achieve both backward security (The revoked user cannot decrypt any new cipher text that requires the revoked attribute to decrypt) and forward security(The newly joined user can also decrypt he previously published cipher texts, if it has sufficient attributes). The scheme does not require the server to be fully trusted, because the key update is enforced by each attribute authority not the server. Even if the server is not semi-trusted in some scenarios, our scheme can still guarantee the backward security. Then, revocable multi-authority CP-ABE scheme is proposed as the underlying techniques to construct the expressive and secure data access control scheme for multi-authority cloud storage systems.},
