In this paper, we introduce an audio encryption scheme based on the cosine number
transform (CNT). The transform, which is defined over a finite field, is recursively applied to …

Multimedia file like audio demands special encryption technique due to its large data
capacity without compromising correlation between it's original and encrypted version …

Fairly recently, a new audio encryption scheme has been proposed. The cryptosystem is
based on a substitution-permutation algorithm using DNA encoding. The key-generation of …

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, a new cryptographic method is proposed, designed for audio files' security.
The encryption algorithm is based on classic symmetric models using pseudo-random …

Transferring multimedia files like audio is a common problem with information security.
Therefore, various encryption technologies are needed to protect these contents. This paper …

This paper presents a robust audio encryption scheme based on three consecutive phases,
accomplished as cyclic shift followed by ciphering and wound up by shuffling, to break the …

Two methodologies for efficient audiovisual data encryption are studied in this research, ie
selective encryption and MHT (multiple-Huffman-table). We first discuss benefits and …

This paper proposes a new approach to the encryption of speech intended to be transferred
on an insecure channel. The proposed technique is based on stream encryption where the …

Audio information strongly correlates in adjacent times, and the data type of the audio is
float, so the traditional encryption algorithms for the image are unsuitable for audio …
