We were fortunate to have this energetic team of experts, and are grateful to all of them for their hard work. The hard work includes very active discussion; the discussion phase was almost as long as the initial individual reviewing. The review and discussion weresupported by a very nice Web-based system, iChair. We appreciate its developers. After all the review phases, 18 papers were accepted for publication in this volume of Advances in Information and Computer Security.Intheworkshop, the contributed papers were supplemented by one invited talk from eminent researcherAlfred Menezes (the Centrefor Applied CryptographicResearch, The University of Waterloo).
