Abstract

SIMPLE AND EFFICIENT BASED ON SECRET POLYNOMIAL METHOD OF SPEECH CRYPTOGRAPHY

*Dr. Hatim Zaini and Prof. Ziad A. Alqadi

ABSTRACT

Protecting the audio file, which may be confidential from intruders, is a very important process. In this paper research a new method of speech cryptography will be introduced, it will be shown how this method is simple and efficient. The proposed method will be implemented to prove that this method is good to be used in data cryptography by giving good values for MSE and PSNR during the encryption and decryption phases. The obtained results of the proposed method will be compared with DES results to show how efficient is the proposed method and how it minimizes the encryption and decryption times. The proposed method will use two private keys: image_ key and secret polynomial to increase the level of security and protection of the speech signal.
