In this paper, we consider scanning and analyzing packets in order to detect hazardous contents using pattern matching. We introduce a hardware perfect-hashing technique to access the memory that contains the matching patterns. A subsequent simple comparison between incoming data and memory output determines the match. We implement our scheme in reconfigurable hardware and show that we can achieve a throughput between 1.7 and 5.7 Gbps requiring only a few tens of FPGA memory blocks and 0.30 to 0.57 logic cells per matching character. We also show that our designs achieve at least 30% better efficiency compared to previous work, measured in throughput per area required per matching character.
