英文摘要：

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 .
