摘要
针对云计算环境带来的安全性问题,在目前云安全模型研究的基础上,对分层的云服务框架模型进行了安全性分析。综合考虑云计算环境特点,在不影响云服务质量的前提下保证数据安全,建立了一个云安全访问控制模型ACCP。该模型利用自动信任协商机制可以不依靠数据中心第三方安全服务,通过双方信任证集的交互和策略的控制自适应地建立组合安全域。通过在用户-服务以及组合服务之间两个场景下信任协商建立过程,表明了模型可行性和有效性。
For improving the security solution in cloud computing,based on the research of cloud security model at present,security problem at layered cloud model is analyzed.With the comprehensive consideration in cloud environment,a access control model-ACCP（ATN cloud computing platform） is proposed,which prove the data in cloud server to be safe without fewer affection on cloud Quos.This model,based on the ATN（automated trusted negotiation） mechanism,independently build the adaptive assorted security domain by translating the trust certificate set and controlling the access stratagem without the assistant from the third security service.By the description in the two scenes,user-services and assorted services,demonstrate the availability and feasibility of the model.
