Row, Row, Row Your Boat: How to Not Find Weak Keys in Pilsung

Chitchanok Chuengsatiansup, Eyal Ronen, Gregory G. Rose, and Yuval Yarom

Abstract

Pilsung is an AES-based North Korean cipher, which uses key-dependent S-Boxes and permutation. The use of pseudo-random ShiftRows permutations gives rise to a potential for weak keys. In this work we show how to build distinguishers to such weak keys and how to effectively search for them. We conclude that no such class of weak keys exist.
