由于时延容忍网络(DTN,delay tolerant networks)时延大,节点无法及时收到私钥更新的广播消息,从而无法及时更新某个时间段的私钥。针对该问题,提出了一个允许私钥自愈的分簇密钥管理方案。该方案不但可以完成对节点私钥的分发与更新,还可以实现节点以前私钥的自愈。安全性与效率分析表明,该方案特别适合网络延时大、间歇性连接的DTN。
Because of the large delay of DTN network
node cannot receive broadcast updating private key messages in a timely manner
thus unable to update the private key for a certain time period.Aiming at this problem
an allowing private key self-healing clustering key was management scheme.The scheme can not only accomplish the distribution of the private keys of node and update
but also can self-heal the old time private keys.Security and efficiency analysis show that the scheme is particularly suitable for large network latency
intermittent connection DTN network.
