Development of New Covert Audio Cryptographic Model
Ziyad Tariq, Mustafa Al-Ta · 2011
New covert cryptography is a different trend in cryptography field, because it has the features: (secrecy, covert, and simplicity). In this paper, a proposed new covert audio cryptographic model is presented by software simulation. The proposed model has the ability to cryptographically hide secret audio messages in image cover. The proposed model was implemented using: (dual secret sharing method in order to obtain secrecy feature, masking technique in order to obtain covert feature, and psychoacoustics effects in order to obtain simplicity feature). The performance of the proposed model has been successfully tested by computer simulation and the results presented both quantitavely and qualitatively. Finally, the proposed model has been implemented between two nodes through the Internet network.
