A NOVEL APPROACH OF SECURE COMMUNICATION BASED ON THE TECHNIQUE OF SPEECH INFORMATION HIDING
I. Introduction and Motivation
Most traditional secure communication relies on the encryption of secret information. Unfortunately ,it is very weak to today's powerful computer, especially to quantum computer. Chaotic secure communication is a hot research area, but it is still in the experimental phase and can not be practically used now. The advance of secure communication is slowed down in recent decades. Information hiding is a new technique of hiding secret information into public information and establishing a subliminal channel for covert communication, i.e. secure communication. This letter proposes a novel approach of secure communication based on the technique of speech information hiding.
