AB Lawful Interception (LI) is a fundamental tool in today's Police investigations.Therefore, it is important to make it as quickly and securely as possible as well as a reasonable cost per suspect. This makes traffic capture in aggregation links quite attractive, although this implies high wirespeeds which require the use of specific hardware-based architectures. This paper proposes a novel Bloom Filter-based monitoring station architecture for efficient packet capture in aggregation links. With said Bloom filter, we filter out most of the packets in the link and capture only those belonging to lawful interception wiretaps. Next, we present an FPGA-based implementation of said architecture and obtain the maximum capture rate achievable by injecting traffic through four parallel Gigabit Ethernet lines. Finally, we identify the limitations of our current design and suggest the possibility of further extending it to higher wirespeeds.- Best Paper Award
