安全功能对于物联网(IoT)至关重要，考虑到资源受限的物联网设置，实施是具有挑战性的。我们开发了一种适用于物联网的轻量级基于身份的加密系统，以实现设备之间的安全认证和消息交换。我们的方案使用物理不可克隆函数(PUF)来生成每个设备的公共身份，该身份被用作用于消息加密的每个设备的公钥。给出了协议的会话密钥安全性和通用可组合框架的形式化证明，证明了该方案对被动攻击和主动攻击具有较强的弹性。我们已经演示了协议实施所需的设置，并表明建议的协议实施产生的硬件和软件开销很低。
Security features are of paramount importance for the Internet of Things (IoT), and implementations are challenging given the resource-constrained IoT setup. We have developed a lightweight identity-based cryp-tosystem suitable for IoT to enable secure authentication and message exchange among the devices. Our scheme employs a Physically Unclonable Function (PUF) to generate the public identity of each device, which is used as the public key for each device for message encryption. We have provided formal proofs of security in the Session Key Security and Universally Composable Framework of the proposed protocol, which demonstrates the resilience of the scheme against passive and active attacks. We have demonstrated the setup required for the protocol implementation and shown that the proposed protocol implementation incurs low hardware and software overhead.
