摘　　要：基于现有的身份认证技术,结合二维条码和蓝牙技术,设计一种安全性高、操作方便的身份认证方法。该方案在认证过程中结合静态口令机制和动态口令机制,用RC对称加密算法提高了算法的效率和加密的安全性,利用Randon变换提取边界进行精确定位的高效的二维条码图像的识别方法,解决了在无线认证系统所面临的安全瓶颈。对该系统的安全性能的分析结果表明,该方案切实可行。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.
