A Digital Signature Scheme for Long-Term Security

Dimitrios Poulakis and Robert Rolland

Abstract

In this paper we propose a signature scheme based on two intractable problems, namely the integer factorization problem and the discrete logarithm problem for elliptic curves. It is suitable for applications requiring long-term security and provides smaller signatures than the existing schemes based on the integer factorization and integer discrete logarithm problems.
