Design of the Identity Authentication and Key Management System Based on Wireless Community

摘要

With the rapid development of wireless communication technology, wireless community has brought a lot of convenience to people's life. However, in the open wireless network environment, the communication system has been attacked and threatened to be higher than the traditional wired network. In order to improve the reliability of the wireless community network identity authentication and the efficiency of the key management system, this paper proposes a bidirectional identity authentication scheme based on one-way hash function and one-time random number, the scheme realizes the two-way authentication between users and servers, and provides a secure key agreement for the server and users. Finally, the wireless community identity authentication and key management system are tested, we found that the authentication method based on the random number is lower than the energy consumption of common authentication mode, and the communication overhead is smaller, the system stability and reliability are also good.
