Resum

It is important to check the integrity of remote data in cloud computing environment. When the user data is large, it need many cloud servers to store it. Thus, it needs the distributed remote data integrity checking. Provable data possession (PDP) is a good method to check remote data integrity. Taking use of ID-based public key cryptography, distributed computing and PDP, we will study ID-based distributed PDP. According to different application requirements, we propose the corresponding security models. At the same time, based on bilinear pairings, we will design many different distributed PDP schemes. These schemes should have their own advantages. Their security will be proved in the random oracle model (ROM) or in the standard model. The efficiency will be estimated according to the computation consumption and communication consumption. At last, the simulation results will be given.
