The abstract for our original paper read "Parallels are drawn between the problems and techniques associated with achieving high reliability, and those associated with the provision of security, in distributed computing systems. Some limitations of the concept of a Trusted Computing Base are discussed, and an alternative approach to the design of highly secure computing systems is put forward, based on fault tolerance concepts and techniques."
We have reprinted the original version of the paper within an encapsulation consisting of an Introduction which describes the historical context in which the paper was written, and a Postscript which explains why we still think our paper is worth reading despite the fact that the historical context no longer applies.
Keywords: reliability, security, fault-tolerance
