摘要
为了保证用户敏感信息的安全性,需要对用户敏感信息进行隐蔽传输。采用已有方法对分层异构网络中的用户敏感信息进行隐藏时,所得信息的完整性和安全性较低。鉴于此,提出一种基于移动切换认证的分层异构网络中的用户敏感信息隐藏方法。该方法采用嵌入单元置乱算法对用户的敏感信息进行置乱,打乱用户敏感信息在分层异构网络中的正常排序序列;根据字符亮度编码机制并结合HSI模型,在打乱的用户敏感信息排序序列内得到最优的用户敏感信息嵌入位置;采用载体操纵法对分层异构网络中用户敏感信息的嵌入单元集合进行分析,根据分析结果将用户的敏感信息嵌入到最优嵌入位置中,完成分层异构网络中用户敏感信息的隐藏。实验结果表明,所提方法得到的信息的完整性和安全性均较高。
In order to ensure the security of users’ sensitive information,it’s essential to transmit the users’ sensitive information in a covert manner.When the current method is used to hide the users’ sensitive information in the hierarchical heterogeneous network,the obtained information has low integrity and low information security.This paper proposed a users’ sensitive information hiding method in hierarchical heterogeneous networks based on mobile swit- ching authentication.It uses the embedded unit scrambling algorithm to scramble the sensitive information of users and disrupts the normal ordering of users’ sensitive information in hierarchical heterogeneous networks.Then, combined with the HSI model,the optimal users’ sensitive information embedding position is obtained within the scrambled users’ sensitive information sorting sequence according to the character brightness encoding mechanism.And the vector-based manipulation method is used to set the embedding unit of users’ sensitive information in the hierarchical heterogeneous network.According to the analysis results,users’ sensitive information is embedded in the optimal embedding position,and the users’ sensitive information hiding in the hierarchical heterogeneous network is completed.The experimental results show that the information obtained by the proposed method has high integrity and security.
