Pattern Matching
An important subtask of the pattern discovery process is pattern matching, where the pattern sought is already known and we want to determine how often and where it occurs in a sequence. In this paper we review the most practical techniques to find patterns of different kinds. We show how regular expressions can be searched for with general techniques, and how simpler patterns can be dealt with...
متن کاملFast and Simple Character Classes and Bounded Gaps Pattern Matching, with Applications to Protein Searching
The problem of fast exact and approximate searching for a pattern that contains classes of characters and bounded size gaps (CBG) in a text has a wide range of applications, among which a very important one is protein pattern matching (for instance, one PROSITE protein site is associated with the CBG [RK] - x(2,3) - [DE] - x(2,3) - Y, where the brackets match any of the letters inside, and x(2,...
متن کاملEfficient Fpga-based Regular Expression Pattern Matching
An approach to the automatic generation of efficient Field Programmable Gate Arrays (FPGAs) circuits for the Regular Expression-based (RegEx) Pattern Matching problems is presented. Using a novel design strategy, as proposed, circuits that are highly area-and-time-efficient can be automatically generated for arbitrary sets of regular expressions. This makes the technique suitable for applicatio...
متن کاملHyperScan, A High-Performance Regular Expression Matching Engine
EXECUTIVE SUMMARY HyperScan is a software pattern matching library that can match large groups of regular expressions against blocks or streams of data. Ideal for applications that need to scan large amounts of data at high speed, such as Intrusion Prevention (IPS), Antivirus (AV), Unified Threat Management (UTM) and Deep Packet Inspection (DPI) systems, HyperScan runs entirely in software and ...
متن کاملRegular Expression Matching on Graphics Hardware for Intrusion Detection
The expressive power of regular expressions has been often exploited in network intrusion detection systems, virus scanners, and spam filtering applications. However, the flexible pattern matching functionality of regular expressions in these systems comes with significant overheads in terms of both memory and CPU cycles, since every byte of the inspected input needs to be processed and compare...
