Twin RSA

Arjen K. Lenstra and Benjamin M. M. de Weger

Abstract

We introduce {\em Twin RSA}, pairs of RSA moduli $(n,n+2)$, and formulate several questions related to it. Our main questions are: is Twin RSA secure, and what is it good for?

Note: The November 11, 2005, update includes Sophie Germain RSA (n,2n+1), big brother RSA (n,n+2,2n+1), and remarks on other similar generalizations.
