Abstract: Based on identity authentication technique of nowadays, integrates the technology of 2D barcode and bluetooth, an ID authentication method for wireless network is designed. The method has finer security and operated conveniently. The scheme joins the static-password mechanism and the dynamic-password mechanism in the process of the authentication, with RC symmetric encryption algorithm improving this method’s efficiency and security, and adopts an efficient method of image recognition in 2D barcode, which is using Randon transformation getting the edge to improving precise positioning, it successfully solves the problem of security in wireless identity authentication. Analysis result proves the scheme is reliable via the analysis of security capability of this system.
