    摘要:

    物联网作为一种新型通信网络的发展与应用,承载着大量敏感信息的安全传输与存储.由于物联网设备资源有限,通信开销大、传输速率慢且需存储敏感信息的安全原语(如公钥算法、数字签名等)不适用于轻量级设备的认证.本文利用物理不可克隆函数(PUF)所具备防篡改防克隆的特性来生成共享密钥,结合MASK算法、Hash函数等安全原语,为物联网设备提出一种轻量级匿名密钥共享认证协议.通过Ban逻辑和形式化工具ProVerif进行安全分析验证,证明该协议能够防御中间人攻击、去同步攻击、假冒攻击、建模攻击等.通过对比其他协议,该协议具备计算成本低、通信开销和存储容量小以及安全性能高的特点,适合于资源受限设备的安全通信传输.

    Abstract:

    With the development and application of communication networks, the Internet of Things carries the safe transmission and storage of a large amount of sensitive information. Since devices are usually small in size and resource-constrained, complex security primitives are not suitable for authentication of lightweight IoT devices. This paper proposes a lightweight anonymous key shared authentication protocol for IoT devices, which generates a shared key by the physical unclonable function(PUF) and uses security primitives such as the MASK algorithm and the Hash function. The security analysis and verification are accomplished by Ban logic and ProVerif to prove that the protocol ensures security attributes such as anonymity, non-repudiation, and forward/backward confidentiality. Compared with other protocols, this protocol has the characteristics of low computing cost, small communication overhead and storage capacity, and high security performance, which is suitable for the secure communication transmission of resource-constrained devices.
