Cryptanalysis and Design of Block Ciphers
This thesis focuses on cryptanalysis techniques and design of block ciphers. In particular, modern analysis methods such as square, boomerang, impossible differential and linear attacks are described and applied to real block ciphers. The first part of this thesis concentrates on the two most relevant modern cryptanalysis techniques: linear and differential cryptanalysis. These and related tech...
متن کاملOn the Design of Secure Block Ciphers
In this paper, we examine a class of block ciphers referred to as substitutionpermutation networks or SPNs. We assert that the basic SPN architecture can be used to provide an efficient implementation of a secure block cipher if the system S-boxes are carefully selected and connected with an appropriate linear transformation. Specifically, it is shown that S-boxes which possess good diffusion a...
متن کاملBlock Ciphers And Cryptanalysis
This report gives a basic introduction to block cipher design and analysis. The concepts and design principles of block ciphers are explained, particularly the class of block ciphers known as Feistel ciphers. Some modern block cipher cryptanalysis methods are demonstrated by applying them to variants of a weak Feistel cipher called Simplified TEA (STEA), which is based on the Tiny Encryption Al...

متن کاملCryptographic Functions and Design Criteria for Block Ciphers
Most last-round attacks on iterated block ciphers provide some design criteria for the round function. Here, we focus on the links between the underlying properties. Most notably, we investigate the relations between the functions which oppose a high resistance to linear cryptanalysis and to differential cryptanalysis.
