Abstract:
In this paper we present a Diffie-Hellman key exchange implementation using stÃƒÂ©ganographied images. The
Diffie-Hellman key exchange requires the use of digital signature or creating a secure channel for data exchanging to avoid
the man in the middle attack. But the using steganography made invisible the data exchange to a potential attacker. This
approach has never been proposed and allowed us to generate a symmetric 128-bit key between two users without use of
digital signature or secure channel. However, it works only on bitmap images, heavy images and sensitive to compression.
