Evidential Quality Preserving of Electronic Record in Cloud Storage

Abstract

Cloud storage is now a hot research topic in information technology, which has changed the technical architecture and implementation method of electronic records management. However, due to loss of physical control of the electronic record in cloud storage environment, it is more difficult to guarantee the evidential quality for manager. In this paper, we analyzes the requirements of evidential quality preserving for electronic record in cloud storage based on information security theory. Moreover we construct the first technology framework of the evidential quality preserving for electronic record in cloud storage. In addition, the integration method to insure the authenticity, integrity, and reliability of electronic records, which is an serious technical challenge, in cloud storage is studied. Finally, we present the first evidential quality preserving shcheme of electronic record based on Diffie-Hellman key agreement and provable data possession.
