Automatic Protocol Signature Generation Framework for Deep Packet Inspection

The authors present an automatic application protocol signature generating framework for Deep Packet Inspection (DPI) techniques with performance evaluation. They propose to utilize algorithms from the field of bioinformatics. They also present preprocessing methods to accelerate their system. Moreover, they developed several post-processing techniques to refine the accuracy of the results. Finally, they 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.
