“…In this section, the proposal is compared with other works, first comparison depends on key space, the second depends on MSE and PSNR, and the third depends on consumed timed through encryption process, Table III, Table IV III that key space of proposal is better than [6] and less than [7]. Also the proposal is compared with [7] and [8] regarding to the MSE and PSNR values between original and decrypted signal, Table IV shows average of MSE equal to 0, and average PSNR value of the proposal , which indicates the perfect retuned of voice signal. Finally, the proposal is compared with [7]and by estimating time of encryption for 12500KB voice data , it's obvious from Table V that time of proposal is better than time obtained by [7].…”

Voice over Internet Protocol (VoIP) calls are susceptible to interfere at many points by many attackers, thus encryption considered an important part in keeping VoIP. In this paper, Encryption VoIP based on Generated Biometric Key for RC4 Algorithm is proposed to encrypt the voice data before transmitting it over the network. The system uses a stream algorithm based on RC4 encryption with the new method of biometrics based Key generation technique. This system has generated complex keys in offline phase which is formed depend on features extracted using Linear Discernment Analysis (LDA) from face images. The experimental work shows that the proposed system offers secrecy to speech data with voice cipher is unintelligible and the recovered voice has perfect quality with MSR equal to zero and PSNR equal to infinity.

“…Chaotic maps have been utilized by several groups for textual content encryption. In particular, Ekhlas et al [ 9 ] proposed a textual content-encryption approach based on block cipher and chaotic maps. Their algorithm encrypted/decrypted an 8 × 8 bytes block primarily based on permutation and substitution the byte in S-box.…”

Chaos-based encryption has shown an increasingly important and dominant role in modern multimedia cryptography compared with traditional algorithms. This work proposes novel chaotic-based multimedia encryption schemes utilizing 2D alteration models for high secure data transmission. A novel perturbation-based data encryption for both confusion and diffusion rounds is proposed. Our chaotification structure is hybrid, in which multiple maps are combined combines for media encryption. Blended chaotic maps are used to generate the control parameters for the permutation (shuffling) and diffusion (substitution) structures. The proposed schemes not only maintain great encryption quality reproduced by chaotic, but also possess other advantages, including key sensitivity and low residual clarity. Extensive security and differential analyses documented that the proposed schemes are efficient for secure multimedia transmission as well as the encrypted media possesses resistance to attacks. Additionally, statistical evaluations using well-known metrics for specific media types, show that proposed encryption schemes can acquire low residual intelligibility with excessive nice recovered statistics. Finally, the advantages of the proposed schemes have been highlighted by comparing it against different state-of-the-art algorithms from literature. The comparative performance results documented that our schemes are extra efficacious than their data-specific counterpart methods.
