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

open access: yesJournal 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.

Connecting the Complexity of MQ- and Code-Based Cryptosystems [PDF]

open access: yesTatra Mountains Mathematical Publications, 2017
Abstract We study the connection between the MQ problem and the de­coding problem, through the intermediate MRHS representation. The main goal of this study is to explicitly bound the complexity of solving MQ systems with decoding tools.

A framework for cryptographic problems from linear algebra

open access: yesJournal of Mathematical Cryptology, 2020
We introduce a general framework encompassing the main hard problems emerging in lattice-based cryptography, which naturally includes the recently proposed Mersenne prime cryptosystem, but also problems coming from code-based cryptography.

Secure and Compact: A New Variant of McEliece Cryptosystem

open access: yesIEEE Access
This paper introduces a variant of the McEliece cryptosystem and employs the $(C_{1}, C_{1} + C_{2})$ -construction to generate a new code from two arbitrary linear codes. We propose an efficient hard-decision decoding algorithm for linear codes derived
