Pattern matching has became a bottleneck of software based Network Intrusion Detection System (NIDS) as the number of signature have recently increased dramatically. Many FPGA-based architectures for detecting malicious patterns have been proposed recently. However, these approaches have just considered matching pattern separately while more and more complex combination of several patterns are utilized...
Perl Compatible Regular Expression (PCRE) is increasingly used in Network Intrusion Detection System due to its efficiency. However, there are many issues that have not been completely solved for PCRE matching on hardware platform. In this paper, we propose an FPGA-based PCRE matching architecture that effectively improves the constraint repetition, an importance feature of PCRE. We enhance our architecture...
This paper describes a Cuckoo-based Pattern Matching (CPM) engine based on a recently developed hashing algorithm called Cuckoo Hashing. We implement the improved parallel Cuckoo Hashing suitable for hardware-based multi-pattern matching with arbitrary length. CPM can rapidly update the static pattern set without reconfiguration while consuming the lowest amount of hardware. With the power of massively...
