In this paper we present the block cipher Rijndael, which is one of the fifteen candidate algorithms for the Advanced Encryption Standard (AES). We show that the cipher can be implemented very efficiently on Smart Cards.

Threshold cryptosystems use algebraic properties such as homomorphisms in order to allow several parties to jointly evaluate a cryptographic primitive. Several cryptographic primitives, however, avoid -by definition- the use of algebraic properties, or otherwise their security is compromised; this is the case, for instance, of block ciphers, pseudo ...

In this paper we present a new 96-bit block cipher called BKSQ. The cipher can be implemented efficiently on a wide range of processors (including smartcards) and in hardware.

Several DES replacement block ciphers have been published. In this paper a report will be given on the development of a package for analysis and comparison of block ciphers. Experimental results are presented on applying this package to DES, FEAL-N, and Madryga ciphers.

Linear Frameworks for Block Ciphers
Designs, Codes and Cryptography, 2001In the paper linear components in (block) cipher structures are investigated, especially with respect to their role in providing resistance against differential and linear cryptanalysis. The cipher structures studied are similar to the classical Substitution-Permutation networks, however instead of permutations more general linear transformations are ...

This paper describes the MESH block ciphers, whose designs are based on the same group operations as the IDEA cipher, but with a number of novel features: flexible block sizes in steps of 32 bits (the block size of IDEA is fixed at 64 bits); larger MA-boxes; distinct key-mixing layers for odd and even rounds; and new key schedule algorithms that ...

This paper proposes a nested (hierarchical) SPN structure and the symmetric block cipher "Hierocrypt". In the nested SPN structure, lower-level SPN structures are recursively embedded into S-box positions in SPN of the higher level. This structure recursively assures the lower bound of active S-box number, and high security level is efficiently ...

This paper considers modern secret-key block ciphers. The theory behind the design and analysis of modern block ciphers is explained, and the most important known attacks are outlined. Finally the Advanced Encryption Standard is discussed.

In this paper we give a short overview of the state of the art of secret key block ciphers. We focus on the main application of block ciphers, namely for encryption. The most important known attacks on block ciphers are linear cryptanalysis and differential cryptanalysis.
