Opis

The Western European Workshop on Research in Cryptology (WEWoRC 2007) was the second of its kind. It was organizedas a joint venture between the Horst G] ortzInstituteforSecurityinInformationSystems(HGI), andtheSpecialInt- est Groupon Cryptology(FG Krypto) of the German Computer Science Society (Gesellschaft fu ]r Informatik e.V.). The aim was to bring together researchers in the?eldofcryptology.TheworkshopfocusedonresearchfromMastersandPhD students, and brought them together with more experienced senior researchers. The ?rst workshop (WEWoRC 2005) was held in Leuven. WEWoRC 2007 was held in the German Ruhr region, more particularly in Bochum, during July 4-6, 2007. Formerly a mining town, Bochum is currently growing into a knowledge-based economy. Aided by the city council, IT se- rity is a special focus for economic development. Hence, it provided the perfect scenery for hosting this event. In total, we had 81 participants from 13 di?- ent countries (Belgium, Finland, France, Germany, Iran, Japan, Luxembourg, Malawi, Slovenia, Taiwan, Tunisia, UK, USA).
