Executive Summary

This paper presents PICO, a generic infrastructure for secure group communication in Mobile Ad-hoc NETworks (MANETs). PICO provides an intrusion-tolerant group management service, allowing clients to join or leave a logical group and enabling group members to communicate securely using a dynamically generated group encryption key. Since MANETs are characterized by relatively high message loss and frequent network partitions, PICO is built around a new Byzantine fault tolerant agreement protocol designed to cope with these conditions.
