开放式网络常常是变化的和预先不可知的,这使开放网络需要新的信任体系结构来支撑网络的安全。提出了一个新的信任体系结构。信任分为三层:网络信任层、设备信任层和应用信任层。网络信任层是基础,没有网络信任层的信任就没有设备层的信任;同样,没有设备信任层的信任就没有应用信任层的信任。对等层之间的信任关系包括基本信任和经验信任。使用模糊理论评估经验信任值,定义了新的连接算子和合并算子用于模糊评估推荐信任值。结果表明,该信任体系结构适合在开放网络环境下建立信任关系,为开放网络安全提供了一种新的解决思路。
Open networks are often changing and unpredictable, making open networks require new trust architectures to support cyber security. Proposed a new trust architecture. Trust is divided into three layers: network trust layer, device trust layer and application trust layer. The network trust layer is the foundation. There is no trust in the device layer without trust in the network trust layer. Likewise, there is no trust in the trust layer without trust in the device trust layer. The trust relationship between the peers includes basic trust and experience. Using the fuzzy theory to evaluate the empirical trust value, a new connection operator and a merge operator are defined for fuzzy evaluation of the recommended trust value. The results show that the trust architecture is suitable for establishing trust relationship in open network environment and provides a new solution to open network security.
