This paper presents the design of a secure and fault-tolerant CORBA datastore based on the Fragmentation-Redundancy-Scattering (FRS) technique. This technique consists in fragmenting the confidential data and scattering the resulting fragments across several archives. The FRS-Datastore service interacts with the other CORBA services, in particular with the Persistence, Security and Trading services. One of our goals is to gain a better understanding how the FRS technique can be applied to an open environment prone to crashes and network partitions and using exclusively standard invocations.
