FDP Techniques in Object-oriented Systems
Brian Randell, J-C Fabre · Computing Laboratory Technical Report Series · 1991
The technique termed Fragmented Data Processing (FDP) [Fray and Fabre 1989], [Deswarte, Blain et al. 1991], [Trouessin, Fabre et al. 1991] is a new approach to the combined provision of overall system security (in the sense of data and processing confidentiality) and reliability in distributed systems. It can provide each of the users of a distributed system with an individual set of processing and storage resources which are to a great extent protected not only from the effects of hardware and software faults but also of so-called intrusions. By this term we mean (presumably) deliberate attempts by other (possibly unauthorized) users of the system to gain information from, or modify, or deny access to, the user's resources. For example, such attempts could even involve tampering physically with the hardware, or inserting Trojan Horse software.
