Communication security has always played a large role in human affairs, and is a fact of daily life in our today's information society. It is provided by cryptography, whose history has been a long history of failures. Constant tension between codemakers and codebreakers brought us increasingly stronger cryptographic techniques, and increasingly better ways to break them. Mathematical cryptographic techniques that we rely on today are not unbreakable. We know that a future quantum computer will break them, and perhaps even a classical cracking method will be found. Can this cat-and-mouse game ever end? Is perfect cryptography ever possible?
