By leveraging the concept of chirality, or the difference of a shape from its mirror image, EPFL scientists have engineered ...

Quantum computing advances in China has led some experts to warn Q-Day may be closer than we think. How safe is our data and ...

Recently, many chaos-based image encryption algorithms have been proposed. Most of them adopt the traditional confusion-diffusion framework. Multiple encryption rounds or one round of complex ...

VPN protocols are essentially what makes a VPN work. In a VPN, the protocol is a specific set of rules that dictate how data is sent between your device and your VPN provider’s server.

To deal with the threat of image privacy leakage in the Internet of things, this paper presents a novel batch images encryption algorithm using the counter mode and a multi-channel processing scheme.

Image-Encryption-and-Decryption-using-AES-algorithm We have successfully developed a program that encrypts and decrypts the image files accurately. This will help in minimising the problem of data ...

The achieved results show a high-performance security level reached by successful encryption of both grey and color medical images. A comparison with various encryption methods is performed. The ...

The prevailing transmission of image information over the Internet of Things demands trustworthy cryptography for high security and privacy. State-of-the-art security modules are usually physically ...

This study proposes a novel color image encryption algorithm based on a 3D chaotic Hopfield neural network and random row–column permutation. First, a 3D chaotic Hopfield neural network is proposed to ...
