Nathan Keller Bar Ilan University Joint with Itai Dinur Orr Dunkelman and Adi Shamir Block Ciphers A block cipher is a set of 2 n permutations indexed by an n bit key K Each permutation works on a space of . CIS 606. Spring 2010. Analyzing Divide-and-Conquer Algorithms. Use a recurrence to characterize the running time of a divide-and-conquer algorithm.. Solving the recurrence gives us the asymptotic running time. Session 4. Contents. Linear cryptanalysis. Differential cryptanalysis. 2. /48. Linear cryptanalysis. Known plaintext attack.
