We present an automatic application protocol signature generating framework for Deep Packet Inspection (DPI) techniques with performance evaluation. We propose to utilize algorithms from the field of bioinformatics. We also present preprocessing methods to accelerate our system. Moreover, we developed several postprocessing techniques to refine the accuracy of the results. Finally, we propose a DPI system, based on approximate string matching, and find it a viable, novel alternative for the refinement of exact string matching algorithm's results.
