On Renyi Entropies and their Applications to Guessing Attacks in Cryptography

Serdar Boztas

Abstract: We consider single and multiple attacker scenarios in guessing and obtain bounds on various success parameters in terms of Renyi entropies. We also obtain a new derivation of the union bound.

Category / Keywords: foundations / brute force guessing attacks, predictability, entropy
