摘要
静态的密钥管理策略难以适应网络动态变化.针对这一问题提出一种基于关联规则的群组密钥管理方案,使用关联规则分析移动分布式网络中密钥之间的关系,通过路由中密钥使用频率挖掘群组密钥之间的频繁关系,根据可信度建立合理的密钥共享方案.在效率上,该方案适应网络动态变化,降低对先验知识的需求,发现频繁密钥集规模与路由延时之间的折中关系,网络实体可根据密钥之间的频繁关系动态调整群组密钥管理方式.在安全性上,节点根据密钥规则选择密钥策略,在频繁密钥集上实施共享密钥协议,提高了安全性.
Static key management strategy is difficult to adapt to the changes of network distribution.This paper proposes a group key management scheme based on association rules,which uses association rules to analyze the relationship between keys in mobile distributed networks,mines the frequent relationship between group keys through the key use frequency in routing,establishes reasonable key association rules according to the reliability,and negotiates the frequently used keys into shared keys through shared key protocol,so as to improve the forwarding efficiency and success rate.In terms of efficiency,the scheme adapts to the dynamic changes of the network,reduces the demand for prior knowledge,finds the compromise relationship between the size of frequent key set and routing delay,and the network entity can dynamically adjust the group key management mode according to the frequent relationship between keys.In terms of security,the node selects the key policy according to the key rules,and implements the shared key protocol on the frequent key set to improve the security.
