WitrynaThe nonlinear invariant attack was introduced at ASIACRYPT 2016 by Todo et al.. The attack has received extensive attention of cryptographic community due to its practical application on the full-round block ciphers SCREAM, iSCREAM, and Midori64. However, the attack heavily relies on the choice of round constants and it becomes inefficient in ... WitrynaFinally, we apply the rotational differential-linear technique to the cryptographic permutations involved in FRIET, Xoodoo, Alzette, and SipHash. This gives significant improvements over existing cryptanalytic results, or offers explanations for previous experimental distinguishers without a theoretical foundation. dashan2009 outlook.comWitrynarapid development recently. Due to their relatively simple key schedule, nonlinear invari-ant attacks have been successfully applied to several families of lightweight block ciphers.
