A Simple Scheme, for Strengthening Product-sum Type PKC

Masao KASAHARA

Abstract

In this paper we present a very simple scheme for strengthening the conventional product-sum type PKC which has been long considered insecure against the various attacks such as the secret key attack, LLL attack, etc. We show that with the proposed strengthening scheme, the securities of the conventional product-sum type PKC's can be much improved.
