A genetic algorithm is used to find the keys of Type II periodic polyalphabetic ciphers with mixed primary alphabets. Because of the difficulty of the ciphertext only cryptanalysi...
The Hill cipher is a classical symmetric encryption algorithm that succumbs to the know-plaintext attack. Although its vulnerability to cryptanalysis has rendered it unusable in p...
The KeeLoq cipher is used in many wireless car door systems and garage openers. Recently the algorithm was studied and several attacks have been published. When a random seed is no...
Building on the work of Kocher[Koc96], Jaffe, and Yun [KJY98], we discuss the notion of side-channel cryptanalysis: cryptanalysis using implementation data. We discuss the notion o...

Matsui's linear cryptanalysis for iterated block ciphers is generalized to an attack called. This attack exploits a weakness that can be described by an e ective partition-pa...
