This novel algorithm employs a shuffling procedure to perform encryption of audio files,
applying the stream cipher method. The algorithm uses a private key to perform encryption …

In this paper, new encryption algorithm for audio file is proposed based on a combination
between block cipher and chaotic maps. The proposed algorithm encrypts and decrypts a …

This paper discusses different nonlinear techniques for removing noise from images; ie,
image denoising. These techniques differ in terms of algorithm design, purpose …

This new algorithm performs lossless image encryption by combining variable-length key-
dependent XOR encryption with S-box substitution. This algorithm was implemented and …

The metrics or measures used in evaluating image quality usually serve applications that
aim at enhancing image appearance or at preventing the image quality from degrading after …
