摘　　要：为了保证密钥分配的安全性,以及密钥分配的可自愈性,提出基于交换节点的电子通信网络自愈式密钥分配。在电子信息通信网络中增添了量子交换机用于交换节点,将不同的密钥分配到不同的用户手中,同时利用量子纠缠态完成信息的携带和传输。采用自愈式密钥分配方案,根据丢失密钥分配会话的前向密钥以及后向密钥,计算未接收密钥。实验结果表明:量子交换机进行交换节点时能量损耗小,且不会对传输的信息产生影响,能够保证密钥实现远距离传输;所提方法能够以较低的通信开销保证密钥的顺利分配;密钥分配时的多种攻击方式均无法获取密钥信息,具有较高的安全性;在密钥分配通信中屏蔽部分通信后,能够实现5次会话密钥的恢复。In order to ensure the security of key distribution and the self-healing nature of key distribution,a self-healing key distribution method based on exchange nodes is proposed for electronic communication networks.Quantum switches have been added to electronic information communication networks for exchanging nodes,distributing different keys to different users,and utilizing quantum entangled states to carry and transmit information.Adopting a self-healing key distribution scheme,the unreceived key is calculated based on the forward and backward keys of the lost key distribution session.The experimental results show:quantum switches have low energy loss when switching nodes,and do not affect the transmitted information,and the long-distance transmission of keys can be ensured;the proposed method can ensure the smooth distribution of keys with low communication overhead;under the proposed method,various attack methods during key distribution are unable to obtain key information,displaying high security;after blocking some communication in key distribution communication,it is possible to recover the session key for 5 times.
