摘要
云计算作为继网格计算、对等计算以及服务计算之后的一种新型计算模式,其异构、虚拟、松散等特性导致了有别于传统计算模式的新的安全问题。为此,从云计算的特点出发,综合回顾并分析了云计算作为新型计算模式所引发的比传统分布式计算更加复杂的安全问题。从边界访问控制、租户间信任、服务质量、虚拟化安全等方面讨论了信任机制与云计算安全的关系,并就如何对云计算环境中的信任进行有效评估问题进行了讨论分析。结合云计算环境下的安全需求,讨论分析了将信任机制引入到云计算环境中的理论依据和可行性,深入剖析了信任机制在云计算背景中不同技术层面的应用。针对当前云计算研究工作中的不足,提出了云计算环境中关于信任机制研究的下一步方向。
Cloud computing has been considered as a new type of computation model after grid computing,peer-to-peer computing and service computing, and its heterogeneous, virtual and loose characteristics leads to new security problems different from the traditional computing model. Therefore, starting from the charactersfics of cloud computing, the more complex security problems in contrast with the traditional distribution computing caused by cloud computing as a new type of computation model are synthetically reviewed and ana- lyzed. The relationship between trust mechanism and security of cloud computing is discussed involving border access control, trust among tenants, service quality and vin＇ualization security etc as well as that of effective evaluation on the trust mechanism in the environment of cloud computation, According to the security requirements of cloud computing environment,the theoretical basis and feasibility for intro- duction of confidence mechanism into cloud computing environment is discussed and analyzed and the applications of trust mechanism in various technical layers in the context of cloud computing is analyzed in depth. In allusion to deficiencies in the present investigations on cloud computing,the research orientation of trust mechanism in environment of cloud computing is also proposed.
