摘要
为了在数据传输过程中,避免机密数据出现泄露的风险,设计了一种无线通信数据隐藏方案。数据隐藏方案在基于物联网的安全通信中发挥着至关重要的作用,数据隐藏使用图像作为输入工具,因为图像易于访问,数据隐藏的目的是确保消息的机密性。提出的方案对物联网中传输的通信数据图像进行整数小波变换,将其解析为四个连续的频带,并评估了用于数据隐藏的HH频带的特征分解值。将提出的方案与传统的编码转换数据隐藏方法在Matlab中进行了仿真,结果表明,与传统方案相比,提出方案具有较高的峰值信噪比,证明了该方案在基于物联网通信中具有较高的应用价值,可保证传输数据的机密性。
In order to avoid the risk of leakage of confidential data in the process of data transmission,a wireless communication data hiding scheme is designed.Data hiding schemes play a vital role in secure IoT⁃based communications,data hiding uses images as input tools because images are easily accessible,and data hiding aims to ensure the confidentiality of messages.The proposed scheme uses integer wavelet transform on the image of communication data transmitted in the Internet of Things,resolves it into four continuous frequency bands,and evaluates the feature decomposition of the HH band used for data hiding.The proposed scheme is simulated in Matlab with the traditional code conversion data hiding method.The results show that compared with the traditional scheme,the proposed scheme has a higher peak signal⁃to⁃noise ratio,which proves that the scheme has a higher application value in the communication based on the Internet of Things,and can ensure the confidentiality of the transmitted data.
