A ZigBee network anonymous authentication scheme based on Chebyshev chaotic mapping and CRT

针对ZigBee网络信任中心不完全可靠、入网时缺乏身份认证等问题,提出了一种基于Chebyshev混沌映射和中国剩余定理(CRT,Chinese remainder theorem)的ZigBee网络匿名认证方案。该方案不仅能实现匿名身份的双向认证,还可以保障ZigBee网络结构动态变化时密钥分发的安全;其主要基于一个ZigBee与NB-IoT的无线异构网关,使服务器能够通过该网关对网络中的节点进行有效的管理。从安全性分析以及与其他相关文献对比结果可以看出,所提方案具有更高的安全性,还具有匿名性、不可链接性。此外,实验结果表明所提方案在计算开销上较其他方案有更大的优势。

A ZigBee network anonymous authentication scheme based on Chebyshev chaotic mapping and Chinese remainder theorem(CRT)was proposed to solve the problems such as the incomplete reliability of ZigBee network trust center and the lack of identity authentication when accessing the network.The proposed scheme can not only realize two-way authentication of anonymous identity,but also ensure the security of key distribution when ZigBee network structure changes dynamically.It is mainly based on a ZigBee and NB-IoT wireless heterogeneous gateway,so that the server can effectively manage the nodes in the network through this gateway.From security analysis and comparison with other related literature,the proposed scheme has higher security,with anonymity and unlink ability.In addition,the results show that the proposed scheme has more advantages than other schemes on the computational overhead.
