“…That means any change even if very slight change in the starting condition lead to make change in output of the system, this called the sensitivity of the initial state [10]. Lorenz system has the characteristic of the chaotic system which mathematically represented in the three dimensional equations as the following [11]:…”

The huge development in communication, multimedia and networks technologies lead to huge increase in using and transmitting of digital video, with that development the need for securing of these digital data is increased. Video encryption is vastly used to provide security for digital video. In this paper a system for secure video exchange is suggested, which consist of proposed video encryption method based on stream cipher and chaotic system as a key generator. Chaotic systems have been used successfully with cryptography. Chaotic system has characteristic make it suitable to be used in encryption such as pseudo-randomness, and sensitivity to initial conditions. Secure Video exchange system with proposed video encryption method have been successfully designed and implemented, the analysis results and tests on the system demonstrated that the encryption method has good results in term of speed and security.

In this paper a new speech encryption system is presented. It is based on permutation and substitution of speech samples using secret keys in time and transform domains. The system is with multilevel to increase the security and to present an encrypted signal with low residual intelligibility. The logistic map is employed in keys generation to generate permutation and mask keys to be used in the permutation and substitution process. In order to maximize the benefits of the permutation process for the system, Arnold cat map is applied to permute the samples in the last level of encryption system. Simulations results are presented in the paper indicate that the encryption system provides encryption speech signal of low residual intelligibility, key sensitivity and high quality recovered signal. Total key space for the proposed encryption system is (2^3 48 ), which is large enough to protect the encryption signal against brute-force attack.

A new algorithm suggested for audio file encryption and decryption utilizing integer wavelet transform to take advantage of the property for adaptive context-based lossless audio coding. In addition, biometrics are used to give a significant level of classification and unwavering quality because the procedure has numerous qualities and points of interest. The offered algorithm utilized many properties of hand geometry estimations as keys to encode and decode the audio file. Many tests were carried out on a set of audio files and quality metrics such as mean square error and correlations were calculated which in turn confirmed the efficiency and quality of the work.
