Hidden Data Transmission Using Open Channels

Project is devoted to develop a method of hidden data transmission using open channels. Three safety data transmissions were allocated. The first is the concealment of the source and the recipient of the information. The next is hiding the information itself from outside observers. The latter is a concealment of the fact of information transfer. The paper has studied traditional approaches to concealing data and interacting sides. The general idea is to use a network intermediary. In the overview part, we consider such standard mechanisms using the concept of an intermediary, as a proxy server, a virtual private network and anonymous networks. Botnets are also considered as an example of a client-server system, one of the important tasks of which is to hide the command server for which various protocols are used, such as, for example, irc. In this paper, we present an overview of methods for concealing the fact of data transmission, describing approaches to their implementation, the specifics of interaction, strengths and weaknesses. Implementation of such methods involves the use of open channels through which data is transmitted. These two concepts, the method and the channel are inextricably linked and must take into account each other's features. Given the provided methods of protecting information that can be applied to solve problems. Social networks, standard network services and irc protocol were considered. The following describes the choice of hardware and software. The paper contains 38 pages, 3 chapters, 16 illustrations, 1 tables, 17 bibliography items, 4 appendices. Keywords: steganography, data hidden, irc, dns.
