Pattern matching plays an important role in intrusion detection system. Based on analysis and discussions for BM, BMH and BMHS algorithms, an improved algorithm is proposed. The improved algorithm takes advantage of position information of the last character and its adjacent character in current attempt window to get bigger jump distance in each jump so to make the algorithm more efficient. Experimental results show that the number of character comparisons and windows shifts of improved… CONTINUE READING
