Information transfer security based on steganography
Yiqi Dai · Journal of Tsinghua University(Science and Technology) · 2005
The security of information transfers is an important focus in informatics. This paper describes a hybrid method combining steganography with traditional encryption to guarantee information security. The system guarantees information transfer security with a shorter key and simple encryption and hiding. Informatics analysis shows that this hybrid approach is very secure. Since this approach is very simple, it is much more effecient than symmetric encryption schemes. The method provides an effective method for customers who have limited computational ability to guarantee the security of their Chinese information transfers.
