Universal security; from bits and mips to pools, lakes -- and beyond

Arjen K. Lenstra, Thorsten Kleinjung, Emmanuel Thomé

Abstract: The relation between cryptographic key lengths and security depends on the cryptosystem used. This leads to confusion and to insecure parameter choices. In this note a universal security measure is proposed that puts all cryptographic primitives on the same footing, thereby making it easier to get comparable security across the board.
