The ISG/ Smart Card Centre (SCC) is proud to be selected as the host of the 6th Workshop in Information Security Theory and Practices (WISTP 2012). The event will be held in June 19-22 in Royal Holloway. The ISG Smart Card Centre (SCC) played a pivotal role (along with colleagues from France, Belgium and Greece) in bringing this workshop into existence. The workshop’s steering committee has managed to make this event successful, recognised and equally important an event that bridges theory and practice in the field of Information Security. It is a testimony to this success that every year the conference presents a strong academic programme, the publisher for the conference proceedings is Springer and the event’s programme committee along with the invited speakers are drawn from international experts in the field.
