CryptoStego — A novel approach for creating cryptographic keys and messages
This paper proposes a cryptographic key establishment method based on set of images shared by sender and receiver. The method is simple, fast and secure. We call it CryptoStego. Possible key sizes are virtually limitless. Proposed method is implemented in C programming language. The implementation is compared with (A)RC4 stream cipher, by comparing CPU time and memory occupation by both algorithms. The results of comparison are presented. Intel VTune Amplifier XE 2011 was used as measuring tool.
