Key management scheme for bottleneck Steiner tree based Cloud Computing

摘要

Cloud Computing has the ability of providing as many resources as users' needing. This advantage makes that Cloud Computing become a popular service platform. When users use this platform, they could consider two important factors: the efficiency and the security. In this paper, we turn to bottleneck Steiner tree to deal with the efficiency problem and we use key management scheme to achieve security. We mainly work on how the keys are established and renewed. Using qualitative analysis, we show that the proposed schemes can achieve outstanding performance in the latency and security aspects.
