Abstract

In this paper, an asymmetric audio and image encryption mechanism using QR decomposition and random modulus decomposition (RD) in the Fresnel domain is proposed. The audio file is recorded as a vector and converted to a two-dimensional array to act as an image or a sound map. This sound map is encrypted using the image encryption algorithm proposed in this paper. The proposed cryptosystem is validated for both audios and grayscale images. Fresnel parameters and the two private keys obtained from QR decomposition and random modulus decomposition (RD) form the key space. Computer-based reproductions have been carried out to prove the validity and authenticity of the scheme. Simulation results authenticate that the scheme is robust and efficient against various attacks and is sensitive to input parameters.

基于菲涅耳域QR分解和随机模量分解的音频图像加密方案

本文提出了一种基于菲涅耳域QR分解和随机模分解的非对称音频和图像加密机制。音频文件被记录为矢量并转换为二维数组以充当图像或声音地图。该声图采用本文提出的图像加密算法进行加密。所提出的密码系统对音频和灰度图像都进行了验证。由菲涅耳参数和QR分解和随机模分解(RD)得到的两个私钥构成密钥空间。在计算机上进行了复制，以证明该方案的有效性和真实性。仿真结果验证了该方案对各种攻击的鲁棒性和有效性，并且对输入参数敏感。
