Research of Group Key Management Based on Association Rules
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.
