Enhancing the security of a gateway through steganography

Abstract

Securing information is a paramount feature in the world of internet where there is consistence enormous flow of information. With everyone having access to the same internet, sensitive information needs concealment from adversaries. Especially in an environment like the military, information confidentiality and data integrity in a tactical communication network is a priority. A gateway is a technology developed for the South African Defence Force (SANDF) for achieving interoperability between SANDF static and tactical communication networks; the gateway provides a common information communication model for the transmitting of video, voice and data between different communication networks. In this paper, we study the enhancement of security measures between gateways deployed in a tactical network with respect to video streaming. Ongoing research has proven that steganography combined with existing encryption techniques can provide increased security. Steganography is a technique used to conceal the existence of information from detection by unauthorized users. A focus of this study is on video steganography techniques with respect to the measurement of the performance metric namely level of security. A theoretical comparison of the findings from this survey is discussed and the best suitable method for the gateway is presented.
