摘要： 近年来,在安全可信的应用程序所生成的网络信息流中应用隧道实现信息隐蔽,已成为构建隐蔽通信信道的常见技术手段。随着隐蔽信道技术的发展,基于各类不同应用程序的隐蔽信道系统被相继提出,但当前综述多聚焦于深入探讨其技术原理和定义,在分类的详细解析上略显不足,并且缺乏对分类依据以及各类系统优缺点的详尽阐述。因此,对基于应用程序的隐蔽信道这一领域进行全面并深入的综述。从底层应用程序角度出发,将其分为多媒体流应用程序型和实时在线游戏型两大类。依据嵌入隐蔽数据所处环节的不同,将基于多媒体流应用程序的隐蔽信道分为在原始多媒体流中嵌入和在压缩多媒体流中嵌入两类方法。此外,通过深入细致地分析各类方法所具备的独特优势及潜在问题,对多种基于多媒体流的隐蔽信道进行多维对比分析,旨在揭示各类隐蔽信道技术的特性与差异。在现有研究的基础上,归纳总结该领域核心挑战并展望未来发展趋势。

Abstract: Recently,tunneling covert information in the network information flow generated by secure and trusted applications has become a prevalent technique for building covert channels.With the development of covert channel technology,a variety of application-based covert channel systems have been proposed.However,existing reviews predominantly focus on the principles and definitions of the application-based covert channel technologies,omitting detailed explanations of the classification criteria and the strengths and weaknesses of various systems.Consequently,this paper gives a comprehensive and profound review of the field of application-based covert channels.From the perspective of the underlying applications,these covert channels are classified into two categories:those based on multimedia streaming applications and those based on real-time online games.Further,based on the different stages of embedding covert data,the covert channels based on multimedia streaming are subdivided into two types of methods:embedding in the original multimedia stream and embedding in the compressed multimedia stream.In addition,by conducting an in-depth analysis of the unique advantages and potential problems of each method,a multi-dimensional comparative analysis of covert channels based on multimedia flow is established,aiming to reveal the characteristics and differences of various covert channel technologies.Building on the prior research,the prevailing challenges and prospective development trajectories in this field are delineated.
