This book constitutes the refereed proceedings of the First European Public Key Infrastructure Workshop: Research and Applications, EuroPKI 2004, held on Samos Island, Greece in June 2004. The 25 revised full papers and 5 revised short papers presented were carefully reviewed and selected from 73 submissions. The papers address all current issues in PKI, ranging from theoretical and foundational topics to applications and regulatory issues in various contexts.
