Conditional Cube Key Recovery Attack on Round-Reduced Xoodyak

ePrint Report: Conditional Cube Key Recovery Attack on Round-Reduced Xoodyak

Mohammad Vaziri, Vesselin Velichkov

Since the announcement of the NIST call for a new lightweight
cryptographic standard, a lot of schemes have been proposed in response. Xoodyak is one of these schemes and is among the finalists of the NIST competition with a sponge structure very similar to the Keccak hash function – the winner of the SHA3 NIST competition. In this paper with conditional cube attack technique, we fully …
