From Higher-Order Differentials to Polytopic Cryptanalysis

Tyge Tiessen

Abstract: Polytopic cryptanalysis was introduced at EUROCRYPT 2016 as a cryptanalytic technique for low-data-complexity attacks on block ciphers. In this paper, we give an account of how the technique was developed, quickly go over the basic ideas and techniques of polytopic cryptanalysis, look into how the technique differs from previously existing cryptographic techniques, and discuss whether the attack angle can be useful for developing improved cryptanalytic techniques.

Category / Keywords: secret-key cryptography / crytpanalysis, block ciphers, higher-order, polytopic
