摘要:

网络安全是物联网技术研究与应用的关键问题,而认证性与隐私性则是网络安全研究中的首要问题。文章针对如何在节点资源受限的物联网应用中同时做到匿名认证与隐私保护,提出一种适用于物联网低带宽环境的匿名认证与隐私保护方案。方案在消息加密和身份认证研究的基础上,利用环签密同时实现消息的加密和签密者身份的匿名认证。文章在随机预言机模型下对方案的正确性、匿名性、签密者身份的可验证性及签名的不可伪造性进行了形式化证明。

Abstract:

Network security is a key issue in the research and application of Internet of Things, while authentication and privacy are primary issues in the network security research. To solve the anonymous authentication and privacy protection problems at the same time in the applications of Internet of Things with limited node resources, this paper proposes an anonymous authentication and privacy protection scheme for low bandwidth Internet of Things environment. The scheme uses ring signcryption to achieve the message encryption and anonymous authentication of signer’s identity on basis of existing message encryption and identity authentication research. This paper proves formally the correctness, anonymity, verifiability of the signer’s identity and unforgeability of the signature of the scheme in the random oracle model.

Key words: Internet of Things, network security, anonymous authentication, privacy protection
