Automatic Compilation Framework for Bloom Filter Based Intrusion Detection

Virus detection at the router level is rapidly gaining in importance. Hardware-based implementations have the advantage of speed and hence can support a large throughput. In this paper we describe an FPGA-based implementation of the Bloom filter virus detection code that is compiled from the native C to VHDL and mapped onto a Virtex XC2V8000 FPGA. Our results show that a single engine tailored for handling virus signatures of length eight bytes can achieve a throughput of 18.6 Gbps while occupying only 8% of the FPGA area.
