Research on ATN - based Trusted Cloud Computing Security Model ⋆

In cloud computing environment, the trust relationship between resources is hard to define. By analyzing the layered framework for cloud service, we find a regulation for building the trust within the two strange entities. Along with this regulation, we propose a 3-layer trust framework for evaluating trust relationship in cloud computing. Combined with trust computing and automated negotiation trust mechanism, a property-based negotiating trust model was established by improving the property-based trust attestation. Discussing the four security properties, this model can provides safe and high-efficient security underpinning for cloud service.
