A Secure Data Management in Distributing Cloud Computing

Penny uses a distributed reputation management system based on EigenTrust to securely manage data labels without the introduction of a central authority. The data labels empower requester peers to avoid downloads of low-integrity data, and allow sender peers to deny low privilege peers to access high confidentiality data. In addition, sender peers may publish and serve their data anonymously, frustrating attacks that seek to single out and target owners of security-relevant data. We have applied Penny to construct a secure, fully decentralized, data management system for traditional data les as well as Resource Description Framework (RDF) data. In this paper, present penny network architecture and their result and analysis.
