Abstract: This letter proposes a wavelength/spatial optical code-division multiple-access system based on quadratic congruence code matrices (QCCM). According to the in-phase cross-correlation of the ...

Abstract: Assume that is a positive integer. If there is an integer such that , i.e., the congruence has a solution, then is said to be a quadratic congruence . If the congruence does not have a ...

Add a description, image, and links to the quadratic-congruence topic page so that developers can more easily learn about it.

( a, b, c ) are integers provided by the user. ( p ) is a prime number also provided by the user. The goal is to find integer solutions ( x ) modulo ( p ).

ABSTRACT: This paper provides a framework that reduces the computational complexity of the discrete logarithm problem. The paper describes how to decompose the initial DLP onto several DLPs of smaller ...
