A New Scheme of Key Management and Authentication for IOT

The paper notes a new scheme of key management and authentication for IOT to solve the security issues,like the date privacy during the communication and the authentication question. Through the program and protocol performance and security analysis,the results show that the scheme can better meet low resource,high interaction rates,high mobility,low data volume environments and the communication protocol security requirements. Through research-based public key authentication key agreement protocol,the scheme adds a tripartite authentication mode to achieve a valid key authentication.
