On Post-Modern Cryptography

Oded Goldreich

Abstract: This essay relates to a recent article of Koblitz & Menezes (Cryptology ePrint Report 2004/152) that criticizes several typical provable security' results'' and argues that the `theorem-proof paradigm of theoretical mathematics is often of limited relevance'' to cryptography. Although it feels ridiculous to answer such a claim, we undertake to do so in this essay. In particular, we point out some of the fundamental philosophical flaws that underly the said article and some of its misconceptions regarding theoretical research in Cryptography in the last quarter of a century.
