Integral Cryptanalysis on Full MISTY1

Explore an in-depth analysis of integral cryptanalysis on the full MISTY1 block cipher in this 23-minute conference talk. Delve into the specification of MISTY1 and trace the history of Higher Order Differential (HOD) attacks. Discover how researchers extended the attack to cover all rounds of the cipher. Examine key concepts such as the Division Property, Bit Product Function, and their applications in cryptanalysis. Learn about the propagation of these properties through the MISTY S-box S7 and the Fl Function. Investigate the key recovery process and understand Bar-On's optimization technique. Gain valuable insights into advanced cryptanalytic techniques and their implications for modern cipher security.
