摘要: There has been many hidden communication techniques proposed in the last few years. The focus was given to steganography build such techniques. Utilizing stego-key(s) hide secret messages into images strengthen security of these However, adopting one available key-agreement protocols, distribute between communicating parties, will destroy infrastructure entire communication. reason is that, protocols perform their transactions on sight, while desirable communications need be completely hidden. In this paper, a key-generation unit added general model. This utilizes new protocol, stego-KA, help support class exchange sego-key(s) covertly. stego-KA protocol based Diffie-Hellman key establishment and significant advantages that communications.
