Neste artigo, são discutidos métodos importantes para criptoanálise da cifra de fluxo baseada em uma classe de geradores de fluxo de chaves. Esses métodos empregam uma abordagem chamada ataque de correlação rápida. Este problema criptográfico é tratado considerando a sua abordagem de codificação de canal equivalente, nomeadamente a descodificação de certos códigos de taxa muito baixa na presença de ruído muito elevado. Uma nova família de algoritmos para o ataque de correlação rápida é apresentada. Os algoritmos são baseados no princípio de decodificação iterativa em conjunto com um novo método para construir verificações de paridade. O objetivo deste artigo é resumir os resultados relatados e comparar alguns dos recentes. Conseqüentemente, a família é comparada com ataques de correlação rápida melhorados recentemente propostos, baseados em métodos de decodificação iterativos. Uma análise do desempenho e complexidade dos algoritmos é apresentada. As compensações correspondentes entre desempenho, complexidade e insumos necessários são apontadas.

Abstract: In this paper, important methods for cryptanalysis of the stream cipher based on a class of keystream generators are discussed. These methods employ an approach called the fast correlation attack. This cryptographic problem is treated by considering its equivalent channel coding approach, namely decoding of certain very low rate codes in presence of very high noise. A novel family of algorithms for the fast correlation attack is presented. The algorithms are based on the iterative decoding principle in conjunction with a novel method for constructing the parity-checks. A goal of this paper is to summarize reported results and to compare some of the recent ones. Accordingly, the family is compared with recently proposed improved fast correlation attacks based on iterative decoding methods. An analysis of the algorithms performances and complexities is presented. The corresponding trade-offs between performance, complexity and required inputs are pointed out.
