摘　　要：提出了基于椭圆曲线签密的物联网安全通信与匿名通信方案,在Random Oracle模型下分析了方案的可证明安全性.与使用典型的签名、加解密算法的交互通信协议进行了效率对比,提出的方案在计算量与通信量上具有较大优势,能更好地满足物联网安全通信协议的需求.方案同样适用于其他计算、存储能力有限,但要求高效率实现的环境,有广阔的应用前景.We proposed a signcryption based secure communication scheme and anonymous communication scheme for the Internet of things and analyzed the provable security of signcryption ,including confidentiality ,unforgeability and non-repudiation in Random Oracle model .As to efficiency analysis ,the scheme achieves remarkable reduction in computational and communication cost compared with other secure protocols based on typical signature and encryption/decryption algorithms .With its superiority in computing and communication cost ,it proves to be more suitable for resource-restricted environment in Internet of things and better satisfies the requirement of secure protocols in Internet of things ,such as key management ,secure routing ,etc .
