A quantum algorithm provides a new way in solving certain computing problems and usually faster than classical algorithms. Here we report an implementation of a quantum algorithm to determine the parity of permutation...

We present several new constructions of differentially 4-uniform permutations over F22 mby modifying the values of the inverse function on some subsets of F22 m. The resulted differentially 4-uniform permutations have...

In this paper, we propose a construction of functions with low differential uniformity based on known perfect nonlinear functions over finite fields of odd characteristic. For an odd prime power q, it is proved that t...

We present a new method called the permutation matrix method to perform dense coding using Greenbezger-Horne-Zeilinger (GHZ) states. We show that this method makes the study of dense coding systematically and regula...

A highly practical parallel signcrypUon scheme named PLSC from trapdoor permutations (TDPs for short) was built to perform long messages directly. The new scheme follows the Idea "scramble all, and encrypt small",...
