Multi-Cloud Data Management using Shamir's Secret Sharing and Quantum Byzantine Agreement Schemes

摘要: Cloud computing is a phenomenal distributed paradigm that provides flexible, low-cost on-demand data management to businesses. However, this so-called outsourcing of resources causes business security and privacy concerns. Although various methods have been proposed deal with these concerns, none relates multi-clouds. This paper presents practical model in public private multi-cloud environment. The BFT-MCDB incorporates Shamir's Secret Sharing approach Quantum Byzantine Agreement protocol improve trustworthiness storage, without compromising performance. performance evaluation carried out using cloud simulator called CloudSim. experimental results show significantly better terms storage retrieval compared other common cryptographic based models. on CloudSim experiments demonstrates the feasibility model.
