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 ...

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 ...

Most of the current symmetric cryptographic algorithms are deterministic algorithms, i.e., for a given plain text and key mix, the encryption dependably results in the same cipher-text. The attacker can misuse this deterministic nature of symmetric block encryption algorithms by carrying cryptanalysis.

We did not design Rijndael from scratch. In fact, prior to the design of Rijndael, we had already published three block ciphers that are similar to Rijndael. Each of these ciphers inherits properties from its predecessor and enriches them with new ideas.

A block cipher on its own is rather limited.It takes a b-bit string and outputs a b-bit string under the action of a secret key. But what happens when the message we wish to encrypt is 37 bits long and is too small to fill an entire block? What happens if the message is too long for a single block?
