• Abstract

  In this note we deal with the problem of long-term cryptographic security. We discuss briefly the methods of multiple encryption and signature, and the future influence of Quantum, DNA and Chaos methods in cryptography. Moreover, we propose an encryption and a signature scheme based on the problems of integer factorization and discrete logarithm suitable for applications needing long-term security.
