Guidelines

To study modern versions of attacks on bloch ciphers based on differetial cryptanalysis, e.g. rectangle attacks, bumerand attacks and sendwich attacks. To implement some of the published attacks. To analyze some of modern proposals of block ciphers. Emphasis should be made of ciphers used in GSM phones a lighweight cryptography.
