Dispersive Full-Channel Jones Matrix Modulation in Elliptical Polarization Bases via a Single-Layered Metasurface. [PDF]

Adv Sci (Weinh)
This work presents a dispersive full‐channel Jones matrix modulation strategy using single‐layer metasurface. By synergizing wavelength dispersion engineering with elliptical polarization bases, independent control of four Jones matrix channels is achieved across multiple wavelengths.

Cryptanalysis of an Encryption Scheme Based on Blind Source Separation [PDF]

, 2006
Recently Lin et al. proposed a method of using the underdetermined BSS (blind source separation) problem to realize image and speech encryption. In this paper, we give a cryptanalysis of this BSS-based encryption and point out that it is not secure ...

Cryptanalysis of a chaotic block cipher with external key and its improved version [PDF]

, 2006
Recently, Pareek et al. proposed a symmetric key block cipher using multiple one-dimensional chaotic maps. This paper reports some new findings on the security problems of this kind of chaotic cipher: 1) a number of weak keys exists; 2) some important ...

A Brief Retrospective Look at the Cayley-Purser Public-key Cryptosystem, 19 Years Later [PDF]

, 2018
The purpose of this paper is to describe and analyze the Cayley-Purser algorithm, which is a public-key cryptosystem proposed by Flannery in 1999. I will present two attacks on it, one of which is apparently new.
