GuardSec: A Multi-Modal Web Platform for Real-Time Digital Fraud Detection, Entity Verification, and Connection Security Analysis in the African Context

Gilda Rech Bansimba, Regis Freguin Babindamana

Online fraud in Africa has reached an epidemic scale. The few cybersecurity tools that exist are out of reach for ordinary citizens, built almost exclusively for SOC analysts and t…

Integer Factorization: Another perspective

Gilda Rech Bansimba, Regis Freguin Babindamana

Integer factorization is a fundamental problem in algorithmic number theory and computer science. It is considered as a one way or trapdoor function in the (RSA) cryptosystem. To d…

Approximating Euler Totient Function using Linear Regression on RSA moduli

Gilda Rech Bansimba, Regis F. Babindamana, Beni Blaug N. Ibara

The security of the RSA cryptosystem is based on the intractability of computing Euler's totient function phi(n) for large integers n. Although deriving phi(n) deterministically re…

A Continued Fraction-Hyperbola based Attack on RSA cryptosystem

Gilda Rech Bansimba, Regis Freguin Babindamana, Basile Guy R. Bossoto

In this paper we present new arithmetical and algebraic results following the work of Babindamana and al. on hyperbolas and describe in the new results an approach to attacking a R…

A New Hyperbola based Approach to factoring Integers

Gilda Rech Bansimba, Regis Freguin Babindamana, Basile Guy R. Bossoto

From the results in the literature, the algebraic set of the hyperbola with parameter defined by $\mathcal{B}_{n}(X, Y, Z)_{\mid_{x\geq 4n}}= \displaystyle \lbrace \left(X: Y:…
