基于签密技术的ZigBee网络信息安全传输问题研究

Research on ZigBee Network Information Security Transmission based on Signcryption Technology

随着ZigBee技术的广泛应用,网络信息传输安全问题越来越受到人们的重视。在分析ZigBee网络传输消息过程中,对传统的“先签名后加密”方案进行了安全性分析,探究采用签名和加密两种技术结合的签密技术用于传输消息,提出了基于无双线性对无证书签密的ZigBee安全接入认证方案。该方案与传统方案相比,具有较小的计算复杂度、较小的消息扩展率及实现方便简单等优势,特别适合于资源相对受限的ZigBee网络。

With the widespread application of ZigBee technology,the security of network information transmission has attracted more and more attention.In the process of analyzing the message transmission in ZigBee network,this paper analyzes the security of the traditional"signature before encryption"scheme,explores the"signcryption technology"combining signature and encryption for message transmission,and puts forward a ZigBee secure access authentication scheme based on no bilinear pairing and no certificate signcryption.Compared with the traditional scheme,this scheme has the advantages of less computational complexity,less message expansion rate and convenient and simple implementation.It is especially suitable for ZigBee networks with relatively limited resources.
