摘要
根据PE文件资源节的结构特点,总结了资源节中存在的四种冗余,并提出了一种新的信息隐藏方案。新方案综合了四种冗余的优势,采用转移冗余空间的方法,把信息分散隐藏在扩展的资源间的冗余中。分析表明,此方案与已有基于PE文件的信息隐藏方法相比,提高了信息隐蔽性和资源节空闲可利用率。
According to the characteristics of the PE file resources section format, four kinds of redundancies in the resources section were summarized, and a new scheme of information hiding was proposed. The scheme synthesized the advantages about four kinds of redundancies. The information was dispersed into the expanded redundant space between the resources with the method of shift redundant space. This scheme enhanced the information imperceptibility and the resources section redundancies utilization rate, compared with other schemes of information hiding based on PE file.
