The HiPAC project is investigating active, time-constrained databasemanagment. An active DBMS is one which automatically executes specified actions when speciifed conditions arise...
Abstract. We consider the problem of efficient key management and user revocation in cryptographic file systems that allow shared access to files. A performanceefficient solution t...
