摘要
提出一种新型的基于对等网络架构的无集中的安全协作框架 .灵活有效地支持多种安全服务 ,如安全管理、安全数据的存储和共享、安全信息发布等 ;给出了一种适应大规模动态网络环境的支持管理结构自动构造和安全组件自配置的层次和对等方式混合的安全管理方法 ;基于P2P(Peer to Peer)网络的动态特性实现了安全协作框架对于节点变化和安全协作需求的自适应 ;无集中的结构消除了集中管理的性能和带宽瓶颈 ,在网络攻击状态下有较强生存能力 .
A new decentralized security cooperation framework based on P2P (peer-to-peer) network was proposed which supported many kinds of security service such as security management, the storage and sharing of security related data and distribution of security information. A security management method which supports the roboticized construction of management structure and self-configuration of security components under large-scale and dynamic network environment by the mixture of hierarchy and peer-to-peer structure was presented. The dynamic change of security components and requirements of security cooperation is self-adapted with the help of dynamic property of peer-to-peer architecture. Its decentralized architecture eliminates the performance and bandwidth bottleneck of centralized management and has good survivability under node failure and network attack.
