چکیده

In [3] a provably secure synchronous keystream generator based on the Rijndael block cipher is described. This document gives a more general interface for the cipher and investigates effects on the provable security properties.

Improved Analysis of the BMGL Keystream Generator

In this paper we give an improved security analysis of the NESSIE submission BMGL. The new analysis improves also asymptotically some of the theoretical results on which the BMGL keystream generator is based. We also give an alternative, bootstrapped version of the generator which is implementation-wise very close to the original generator and offers even stronger provable security properties.

NESSIE Document NES/DOC/SAG/WP3/018/3∗† About the NESSIE Submission BMGL: Synchronous Key-stream Generator with Provable Security‡

• Using a hybrid argument for probability distributions it is shown that given an adversaryA who is capable of distinguishing the complete pseudorandom sequence (resulting from λ steps of the BMGL generator) from truely random bits (with advantage at least δ) there must exist a related adversary B and a fixed iteration i (of the one-way function f) such that B can distinguish the result of the ...

BMGL: Synchronous Key-stream Generator with Provable Security (Revision 1)

We propose a construction of an efficient, synchronous keystream generator with provable security properties in response to the NESSIE call for primitives. The cryptographic core of the stream cipher is the block cipher Rijndael. We show that a non-trivial attack on the cipher reduces to an attack on Rijndael. The construction uses an optimization of earlier work on pseudorandom generators by B...

Analysis of Implementation Hierocrypt-3 algorithm (and its comparison to Camellia algorithm) using ALTERA devices

Alghoritms: HIEROCRYPT-3, CAMELLIA and ANUBIS, GRAND CRU, NOEKEON, NUSH, Q, RC6, SAFER++128, SC2000, SHACAL were requested for the submission of block ciphers (high level block cipher) to NESSIE (New European Schemes for Signatures, Integrity, and Encryption) project. The main purpose of this project was to put forward a portfolio of strong cryptographic primitives of various types. The NESSIE ...
