Fault and intrusion tolerance in object-oriented systems

Provides a brief overview of a unified technique, called fragmented data processing (FDP), for jointly improving the reliability and security with which distributed computing systems process sensitive information. This technique has already been used to implement various system services in the DELTA-4 distributed system. The paper discusses how FDP can take advantage of an object-oriented design and how it can be applied in object-oriented systems in order to provide fault and intrusion tolerance to ordinary application programs as well as system services
