Analysis and design of block cipher constructions
This thesis is dedicated to symmetric cryptographic algorithms. The major focus of the work is on block ciphers themselves as well as on hash functions and message authentication codes based on block ciphers. Three main approaches to the cryptanalysis of symmetric cryptographic algorithms are pursued. First, several block cipher constructions are analyzed mathematically using statistical crypta...
متن کاملHardware Design and Analysisof Block Cipher Components
This paper describes the efficient implementation of Maximum Distance Separable (MDS) mappings and Substitution-boxes (S-boxes) in gate-level hardware for application to Substitution-Permutation Network (SPN) block cipher design. Different implementations of parameterized MDS mappings and S-boxes are evaluated using gate count as the space complexity measure and gate levels traversed as the tim...
متن کاملUnbalanced Feistel Networks and Block Cipher Design
We examine a generalization of the concept of Feistel networks, which we call Unbalanced Feistel Networks (UFNs). Like conventional Feistel networks, UFNs consist of a series of rounds in which one part of the block operates on the rest of the block. However, in a UFN the two parts need not be of equal size. Removing this limitation on Feistel networks has interesting implications for designing...
متن کاملDesign Principles of the KASUMI Block Cipher
In this paper, we discuss some of theory of provable security against differential and linear cryptanalysis. We also review the design principles of the block cipher KASUMI—especially its resistance against the basic forms of linear and differential cryptanalysis.
متن کاملA New Approach Towards Block Cipher Design
In this paper we apply the cryptographic finite state machine approach as introduced in [1] to the design of symmetric key block ciphers.
