Abstract: In this paper, a color image encryption algorithm based on hyper chaotic Lorenz system and discrete wavelet transform is proposed. The algorithm generates a chaotic sequence using a ...

Two years ago, researchers in the Netherlands discovered an intentional backdoor in an encryption algorithm baked into radios used by critical infrastructure–as well as police, intelligence agencies, ...

Abstract: Aiming at the problems of weak key sensitivity and strong pixel correlation of adjacent pixels in image encryption schemes, This paper constructs an image encryption scheme incorporating a ...

Introduction: Preserving privacy is a critical concern in medical imaging, especially in resource limited settings like smart devices connected to the IoT. To address this, a novel encryption method ...
