An ever increasing number of clients might want to store their information to public cloud servers (PCSs) alongside the quick advancement of distributed computing. New security issues must be illuminated so as to help more customers process their information out in the open cloud. At the point when the customer is limited to get to PCS, he will appoint its intermediary to process his information and transfer them. Then again, remote information honesty checking is additionally a critical security issue out in the open distributed storage. It makes the customers check whether their outsourced information are kept in place without downloading the entire information. From the security issues, we propose a novel intermediary situated information transferring and remote information honesty checking model in identity-based public key cryptography: identity-based proxy-oriented data uploading and remote data integrity checking in public cloud (ID-PUIC). We give the formal definition, framework model, and security display. At that point, a solid ID-PUIC convention is composed utilizing the bilinear pairings. The proposed ID-PUIC convention is provably secure in light of the hardness of computational Diffie–Hellman issue. Our ID-PUIC convention is likewise productive and adaptable. In view of the original client’s authorization, the proposed ID-PUIC protocol can realize private remote data integrity checking, delegated remote data integrity checking, and public remote data integrity checking.
