The present invention provides systems and methods for creating a finite state automata (FSA) (FIG. 1, blocks 110 180) that matches patterns in parallel including the steps of creating states of the automata from a set of patterns to be matched (FIG. 2, blocks 210 280) and passing over the patterns a second time adding transitions to the states to match all the possible that can start within the pattern (FIG. 3, blocks 0 7).
