A note on solitary numbers [PDF]

open access: yesNotes on Number Theory and Discrete Mathematics
Does 14 have a friend? Until now, this has been an open question. In this note, we prove that a potential friend F of 14 is an odd, non-square positive integer.

Factorization of big integer and the security of RSA

open access: yes网络与信息安全学报, 2017
Three kinds of methods for integer factorization were proposed and the security of RSA was demarcated.RSA is a well-known cryptographic algorithm,using the analysis result of those methods.Through the work,readers could easily realize that if merely ...

A New Idea for RSA Backdoors

open access: yesCryptography, 2023
This article proposes a new method to inject backdoors in RSA (the public-key cryptosystem invented by Rivest, Shamir, and Adleman) and other cryptographic primitives based on the integer factorization problem for balanced semi-primes.

Mersenne version of Brocard-Ramanujan equation

open access: yesJournal of New Results in Science, 2023
In this study, we deal with a special form of the Brocard-Ramanujan equation, which is one of the interesting and still open problems of Diophantine analysis.

Conjugacy Systems Based on Nonabelian Factorization Problems and Their Applications in Cryptography

open access: yesJournal of Applied Mathematics, 2014
To resist known quantum algorithm attacks, several nonabelian algebraic structures mounted upon the stage of modern cryptography. Recently, Baba et al. proposed an important analogy from the integer factorization problem to the factorization problem over

A factorization formula for power series [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2014
Given an odd prime p, we give an explicit factorization over the ring of formal power series with integer coefficients for certain reducible polynomials whose constant term is of the form $p^w$ with $w>1$.

Integer LU-factorizations

open access: yesLinear Algebra and its Applications, 1991
The authors give conditions under which a rectangular integer matrix has an integer LU-factorization. They use a modified Gaussian elimination to find the LU-factorization and they consider such factorizations for adjacency matrices of trees.

Key Generation Using Generalized Pell’s Equation in Public Key Cryptography Based on the Prime Fake Modulus Principle to Image Encryption and Its Security Analysis

open access: yesCybernetics and Information Technologies, 2020
RSA is one among the most popular public key cryptographic algorithm for security systems. It is explored in the results that RSA is prone to factorization problem, since it is sharing common modulus and public key exponent.

Improved Outcomes for Older Children, Adolescents, and Young Adults With Neuroblastoma in the Post‐Immunotherapy Era: An Updated Report From the International Neuroblastoma Risk Group

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background We describe clinical and biologic characteristics of neuroblastoma in older children, adolescents, and young adults (OCAYA); describe survival outcomes in the post‐immunotherapy era; and identify if there is an age cut‐off that best discriminates outcomes.
