Network Functions Virtualization (NFV) has received considerable attention in the past few
years, both from industry and academia, due to its potential for reducing capital and …

In recent years, regular expression has been widely used in many network fields, but more
and more applications require real-time update FSM and a space reduced DFA due to …

Network Intrusion Detection Systems (NIDS) make extensive use of regular expressions
(regexes) as attack signatures. Such expressions can be handled in hardware using a bit …

The importance of security infrastructures for high-throughput networks has rapidly grown as
a result of expanding internet traffic and increasingly high-bandwidth connections. Intrusion …

This paper proposes a method using partial reconfiguration to realize a compact regular
expression matching engine, which can update a pattern quickly. In the proposed method, a …

Abstract Recent Network Intrusion Detection Systems (NIDSs) utilize Perl Compatible
Regular Expression to describe malicious patterns existing in the content payload of packets …

Network Intrusion Detection and Prevention Systems (NIDPS) are important elements of
network security. Their role is to monitor internet traffic for malicious content and, on …
