Cloud storage is now a hot research topic in information technology. In cloud storage, date security properties such as data confidentiality, integrity and availability become more important many commercial applications. Recently, provable possession (PDP) schemes are proposed to protect integrity. some cases, it has delegate the remote checking task proxy. However, these PDP not secure since proxy stores state servers. Hence, this paper, we propose an efficient mutual verifiable scheme, which utilizes Diffie-Hellman shared key construct homomorphic authenticator. particular, verifier our scheme stateless independent of service. It worth noting that presented very compared with previous schemes, bilinear operation required.
