Scytale -- An Evolutionary Cryptosystem

CoRR, 2020
With the advent of quantum computing, and other advancements in computation and processing capabilities of modern systems, there arises a need to develop new trapdoor functions that will serve as the foundation for a new generation of encryption schemes. This paper explores the possibility of one such potential trapdoor function using concepts stemming

Seeing Through Scattering With Computational Advances: A Review

Advanced Photonics Research, Volume 7, Issue 6, June 2026.
In scattering media, light scrambles into random speckles and impedes our vision. Unlocking hidden information enables breakthroughs to see behind the opaqueness, inspiring applications in imaging, communication, and encryption. Unlike clear media such as clear water and air, a scattering medium is inhomogeneous, in which propagating photons are ...

Compression Cryptosystem

The Computer Journal
Abstract A compression cryptosystem is a single coding process, the output of which is both reduced in space and secure against unauthorized decoding. Considering both Huffman and arithmetic coding, this paper proposes to apply repeatedly minor changes to the compression model, with negligible deterioration of its optimality.

Deep Optical Cryptography: Joint Encryption and LC Lens Key Generation for Secure Displays

Journal of the Society for Information Display, Volume 34, Issue 5, Page 517-526, May 2026.
We propose a learning‐based visual cryptography system using a liquid crystal modulator for distance‐dependent optical decryption. By jointly optimizing ciphertext images and LC‐based optical keys with shift‐aware training, the framework ensures secure plaintext recovery only at designated distances.

FPGA Realization of a Novel Hyperchaos Augmented Image Encryption Algorithm

IET Computers &Digital Techniques, Volume 2026, Issue 1, 2026.
With the rapid growth of multimedia communication, protecting image data has become increasingly critical. This article proposes a novel 3‐stage hyperchaos‐based augmented image encryption technique (3SHAIET) that utilizes a three‐stage process with chaotic systems of increasing dimensionality (e.g., six‐dimensional [6D], 8D, and 9D) to enhance ...

Cryptanalysis of the Sidelnikov Cryptosystem [PDF]

, 2007
We present a structural attack against the Sidelnikov cryptosystem [8]. The attack creates a private key from a given public key. Its running time is subexponential and is effective if the parameters of the Reed-Muller code allow for efficient sampling of minimum weight codewords. For example, the length 2048, 3rd-order Reed-Muller code as proposed in [

SKE2SG: A Secure Key Establishment Scheme for Smart Grid Cyber‐Physical Systems Based on Elliptic Curve Cryptography

IET Cyber-Physical Systems: Theory &Applications, Volume 11, Issue 1, January/December 2026.
Recent proposals by Mahmood et al., Braeken et al., and Chaudhry et al. aimed at establishing secure communication in AMI, asserting their methods fulfil the requisite security criteria. This paper, however, reveals that each of these proposals exhibits security vulnerabilities and lacks sufficient features for deployment.

A Comparative Study of Decision Tree, RNNs and CNNs for Detection of False Data Injection Attacks in Cyber‐Physical Power Systems

IET Cyber-Physical Systems: Theory &Applications, Volume 11, Issue 1, January/December 2026.
Intrusion detection for FDIAs is proposed using three approaches. (1) a stack‐based model containing an expansion decision tree and neural network, (2) recurrent neural networks (RNNs) and (3) convolutional neural networks (CNNs). The first two methods are based on the initial preprocessing of row instances, whereas the last one involves the time ...
