摘要
密钥管理对整个无线传感器网络安全至关重要,针对该领域现有密钥管理方案存在的问题和层次化路由协议的应用,提出了一种新的无线传感器网络密钥管理方案,基站利用分簇信息为簇分配密钥池,引入网关节点用于簇间安全通信,可用于大规模传感器网络的安全体系。
Key-management is extremely important for security of the whole wireless sensor networks, considering problems existing in some key-management schemes and applications ofhierachical routing protocols, anew key-management scheme for wireless sensor networks is proposed. The base station distributes key-pools for every cluster according to clustering information, gateway nodes are used for secure inter-cluster communication. This scheme is useful for security system of large scale sensor networks.
