The management of private and confidential information is a major problem for dynamic organizations. Secure systems are needed to exchange confidential documents, protect them against unauthorized access and copy with chnages in people's roles and permissions. This paper describes an innovative technical solution with several advantages over approaches based on traditional cryptography and Public Key Infrastructure.

presented at the 14th International Workshop on IEEE DEXA (TrustBus 03) 1-5 September 2003, Prague, Czech Republic
