On the possibility of basing Cryptography on the assumption that $P \neq NP$
Oded Goldreich and Shafi Goldwasser
Abstract: Recent works by Ajtai and by Ajtai and Dwork
bring to light the old (general) question of whether it is
at all possible to base the
security of cryptosystems on the assumption that $\P\neq\NP$.
We discuss this question and in particular review and extend
a two-decade old result of Brassard regarding this question.
Our conclusion is that the question remains open.
Category / Keywords: $\P\neq\NP$, promise problems, smart reductions.
