Providing support for survivable CORBA applications with the Immune system

Abstract

The Immune system aims to provide survivability to CORBA applications, enabling them to continue to operate despite malicious attacks, accidents or faults. Every object within the CORBA application is actively replicated by the Immune system, with majority voting applied on incoming invocations and responses to each replica of the object. Secure multicast protocols are employed to enable the majority voting to be effective, even when processors within the network and objects within the application become corrupted.
