摘要:将物理不可克隆函数(Physical Unclonable Function,PUF)与椭圆曲线上的无证书公钥密码体制相结合,提出一种面向物联网的安全通信方案,在节点设备不存储任何秘密参数的情况下,实现设备间消息的安全传递. 方案无需使用高计算复杂度的双线性对运算,并提供了消息认证机制. 安全性分析表明,该方案不仅能够抵抗窃听、篡改、重放等传统攻击,而且可以有效防范节点设备可能遭到的复制攻击. 对比结果显示,相较于同类方案,该方案明显降低了设备的资源开销.关键词:物联网; 物理不可克隆函数; 椭圆曲线密码; 安全通信; 消息认证Abstract:By combining the Physical Unclonable Function (PUF) with the certificateless public key cryptosystem onthe elliptic curve,a secure communication scheme for IoT is proposed. The secure transmission of messages is realized on thecondition of node devices not storing any secret parameters. The proposed scheme eliminates the need for bilinear pairingwhose computing complexity is high and provides a message authentication mechanism. Security analysis demonstrates thatthe scheme can not only resist the traditional attacks such as eavesdropping,tampering and replay,but also protect the nodedevice from replication attacks. Compared with related schemes,the proposed scheme obviously decreases the resource over-head of devices.Key words:Internet of Things;Physical Unclonable Function (PUF);elliptic curve cryptosystem;secure communi-cation;message authentication
