In this paper, the authors 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 a more efficient solution than the existing ones. Many applications of the Information Technology, such as encryption of sensitive medical data or digital signatures for contracts, need long term cryptographic security. Unfortunately, today's cryptography provides strong tools only for short term security
