En este trabajo se describe una interesante vía para la detección de la existencia de entradas de colisión en el algoritmo de cifrado en flujo RC4 basado en el criterio estricto de avalancha y se discuten los resultados obtenidos en comparación con las debilidades y ataques reportados sobre el RC4 que plantean la existencia de una fuerte correlación entre los parámetros de entrada y salida del algoritmo.Abstract: This paper describes an interesting way for the detection of the colliding entries existence in the RC4 stream cipher algorithm based in the strict avalanche criterion and the results obtained are discussed in comparison with the reported weaknesses and attacks on the RC4 that raise the existence of a strong correlation between the parameters of Input and output of the algorithm.Keywords: strict avalanche criterion, colliding entries, statistical correlation, RC4.References
