We consider t he language L of the st rings over t he alphabet {a, I} of sha pe x lxl where Ixl is t he length of the st ring x . We show that L is recognized in real t ime by an iterat ive array but not by a one-way cellular auto maton , while the lan guage {O, 1}*· L is recognized in real t ime by a cellula r automato n but not by an iterat ive array.

In this paper, four new algorithms for improvements of MD5 and SHA-Keyed/Unkeyed MD5 and Keyed/Unkeyed SHA are proposed. We change the mode of ®xed retrieval of the parameters to that of dynamic retrieval of the parameters by applying a mapping between the index phrase and the parameter table. As shown in the experimental result, with 1% degradation of performance, comparing to the original alg...
