英文摘要: The provable data possession is an efficient method of data integrity verification without downloading the entire data from the cloud and one of the core technologies for implementing secure cloud storage. Based on the theory of certificateless public key cryptography, this project is to explore issues of certificateless provable data possession (CLPDP) scheme in cloud storage. The objectives of this research are listed in the following: 1) to put forward the formal definition and the security model of CLPDP schemes; 2) to design privacy-preserving CLPDP schemes and analyze security formally; 3) to implement a CLPDP prototype based on Hadoop. The innovative study of the project will contribute to the advancement of the theory of provable data possession and provide theoretical basis and technical supports for security issues in cloud storage.
