摘要

The protection of information transmission can effectively improve the security of information in wireless local area network.It is necessary to build a signcryption model of discrete information.Traditional method ignores the detection of the frequency of information code element,resulting in unsatisfactory effect in information protection.In this article,a real time encryption method for secret information of wireless local area network based on elliptic curve is proposed.Firstly,the elliptic curve principle is used to design the private key generator of sender and receiver.Secondly,the secret information is embedded into a text file which is not easy to attract attention of attacker.Then,the dual watermarking is embedded into seal documents to build discrete information signcryption model of secret-involved information system.The frequency of encode element of data in secret-involved information system is detected.Thus,the wireless local area network is encrypted in real time.Simulation results show that the proposed method has high encryption security,which greatly improves the security and stability of secret information in wireless local area network.%对无线局域网信息传输的保护,能够有效提高无线局域网信息安全性.对信息传输的安全保护,需要构建离散信息签密模型,对涉密信息系统进行码元频数检测.传统方法结合无证书签密技术,定义涉密信息数据的长度,但忽略了对信息码元频数的检测,导致信息保护效果不理想.提出基于椭圆曲线的无线局域网涉密信息实时加密方法.利用椭圆曲线原理设计发送方和接收方私钥发生器,将涉密信息嵌入到一个不易吸引攻击者注意的文本文件中,产生双水印,将水印嵌入印章文件,构建涉密信息系统的离散信息签密模型,对涉密信息系统中的信息数据进行码元频数检测,由此进行无线局域网涉密信息实时加密.实验结果证明,所提方法加密安全性高,大幅度提升了无线局域网涉密信息的安全稳定性.
