Blockchain-Based Private Provable Data Possession

Abstract:
In order to check remote data integrity, an important paradigm PDP is proposed. All the existing PDP schemes make use of RSA or bilinear pairings. The huge computation cost and communication cost incurs the inefficient PDP implementation. In other words, they are not practical. In order to solve the problem, we propose a new PDP model: blockchain-based private PDP. The new concept makes use of blockchain which is the core of cryptocurrency. For the new concept, the paper formalizes its system model and security model. Then, a concrete blockchain-based private PDP scheme is designed by making use of blockchain and RSA. The proposed blockchain-based private PDP scheme is provably secure, efficient and practical.
