RSA+: An algorithm at least as secure as RSA. (arXiv:2301.01282v1 [cs.CR])

The RSA algorithm has been around for nearly five decades and remains one of
the most studied public key cryptosystems. Many attempts have been made to
break it or improve it and questions remain about the equivalence of the
strength of its security to well known hard problems in computational number
theory. In this note we propose a modified version which we call RSA+ which is
at least as secure as RSA and show that breaking RSA+ is probably
computationally …
