Alternative Key Schedules for the AES

ePrint Report: Alternative Key Schedules for the AES

Christina Boura, Patrick Derbez, Margot Funk

The AES block cipher is today the most important and analyzed symmetric algorithm. While all versions of the AES are known to be secure in the single-key setting, this is not the case in the related-key scenario. In this article we try to answer the question whether the AES would resist better differential-like related-key attacks if the key schedule was different. For this, we search for …
