基于信息隐藏的无线共享网络数据防篡改方法

Data tamper proof method for wireless sharing network based on information hiding

目前无线共享网络数据海量,造成加密内容与需要保护的数据内容较多,从而导致防篡改成功率较低,为此设计了基于信息隐藏的无线共享网络数据防篡改方法。首先设置基础防御判断用户的可信任度,采集相关的共享数据并对其预处理和编码处理,确定数据传输的优先级。在此基础上制定传输协议,采用分布式的认证结构认证需要传输的数据并计算其安全性增强函数。最后设计隐蔽信道,采用嵌入式算法将待传输的数据隐藏到信道中,以此实现无线共享网络数据防篡改方法的设计。以防篡改成功率、防篡改时间与资源占用情况作为对比指标,所研究的方法有效提高了防篡改的成功率,降低了计算时间与资源占用,满足防篡改需求。

At present,there are a lot of data in wireless sharing network,resulting in more encrypted content and data content that need to be protected,which leads to a low success rate of tamper prevention.Therefore,a tamper prevention method for wireless sharing network data based on information hiding was designed.Firstly,the basic defense was set to judge the user’s trustworthiness,and then the related shared data was collected and preprocessed,and the data transmission priority was determined by coding.On this basis,the transmission protocol was formulated,the distributed authentication structure was adopted to authenticate the data to be transmitted,and the security enhancement function was calculated.Finally,the hidden channel was designed,and the embedded algorithm was used to hide the data to be transmitted into the channel,so as to realize the design of data anti tampering method based on information hiding in wireless sharing network.The results show that the proposed method can effectively improve the success rate of anti tampering,reduce the computing time and resource occupation,and meet the design requirements of anti tampering method.
