Related-Key Boomerang and Rectangle Attacks: Theory and Experimental Analysis KU Leuven
In 2004, we introduced the related-key boomerang/rectangle attacks, which allow us to enjoy the benefits of the boomerang attack and the related-key technique, simultaneously. The new attacks were used since then to attack numerous block ciphers. While the claimed applications are significant, most of them have a major drawback. Their validity cannot be verified experimentally due to their high complexity. Together with the lack of rigorous ...
