Security and Privacy in the Age of Uncertainty covers issues related to security and privacy of information in a wide range of applications including:
*Secure Networks and Distributed Systems;
*Secure Multicast Communication and Secure Mobile Networks;
*Intrusion Prevention and Detection;
*Access Control Policies and Models;
*Security Protocols;
*Security and Control of IT in Society.

This volume contains the papers selected for presentation at the 18th International Conference on Information Security (SEC2003) and at the associated workshops.
