| Abstract | ||
| New covert cryptography is a different trend in cryptography field, because it has thefeatures: (secrecy, covert, and simplicity). In this paper, a proposed new covert audiocryptographic model is presented by software simulation. The proposed model has the abilityto cryptographically hide secret audio messages in image cover.The proposed model was implemented using: (dual secret sharing method in order toobtain secrecy feature, masking technique in order to obtain covert feature, andpsychoacoustics effects in order to obtain simplicity feature).The performance of the proposed model has been successfully tested by computersimulation and the results presented both quantitavely and qualitatively. Finally, the proposedmodel has been implemented between two nodes through the Internet network. | ||
