英文摘要: Research on massive remote data integrity checking is a hotspot in the field of cloud computing security. PDP (Provable Data Possession) is a lightweight remote data integrity probabilistic checking model. The purpose of this project is to address the problems existing in the massive remote date integrity checking in the following aspects: security model and design of ID-based massive remote data distributed PDP, security model and design of ID-based massive remote multi-replica data distributed PDP. The goal of this project can be listed as the following. In theory,for massive remote data in cloud computing, we build up ID-based distributed PDP security models that satisfy different security requirements. Then, based on the different security models, we design ID-based massive remote data distributed PDP schemes, ID-based massive remote multi-replica data distributed PDP schemes. We will prove the security of the proposed schemes in the ROM (Random Oracle Model) or in the standard model. At the same time, we give their computation complexity,communication complexity and storage complexity. Finally, we give computer simulation to test their performance.
