Q 4 Regarding the implementation dates, does that mean all previously established keys have to be changed or that only from that point onwards, newly exchanged keys must use Key Blocks? A All previously established keys can still be used. Key-Block Protection Keys (KBPKs) must be

A Tutorial on Linear and Differential Cryptanalysis
www.cs.bc.eduConventional cryptographic references and texts [11][12][13][14] generally present material on block ciphers in a very descriptive manner, with little detail illustrating the concepts of the attacks. Consequently, most published material detailing the attacks has a research focus and gives little intuition and explanation for the non-expert.
