On Byzantine generals with alternative plans
نویسندگان
چکیده
This paper proposes a variation of the Byzantine generals problem (or Byzantine consensus). Each general has a set of good plans and a set of bad plans. The problem is to make all loyal generals agree on a good plan proposed by a loyal general, and never on a bad plan.

Byzantine Fault Tolerance, from Theory to Reality
Since its introduction nearly 20 years ago, the Byzantine Generals Problem has been the subject of many papers having the scrutiny of the fault tolerance community. Numerous Byzantine tolerant algorithms and architectures have been proposed. However, this problem is not yet sufficiently understood by those who design, build, and maintain systems with high dependability requirements. Today, ther...
متن کاملByzantine Generals and Transaction Commit Protocols
The transaction commit problem in a distributed database system is an instance of the Weak Byzantine Generals problem. It is shown that even under the assumption that a process can fail only by “crashing”—failing to send any more messages—a solution to this problem that can tolerate k failures must, in the worst case, require at least k + 1 message-passing delays. Under this same assumption, a ...
متن کاملByzantine Agreements in Secure Communication
Byzantine Agreements were first formally proposed by Lamport [8], for use in finding faulty processors in distrubuted computer networks. In this article we will use the process of finding faults to uncover traitors in secure communications networks. Maintaining reliability in trusted networks is an important application of Byzantine Agreements. Thus by introducing the fundamentals of the Byzant...

متن کاملAuthenticated Byzantine Generals in Dual Failure Model
Pease et al. introduced the problem of Byzantine Generals (BGP) to study the effects of Byzantine faults in distributed protocols for reliable broadcast. It is well known that BGP among n players tolerating up to t faults is (efficiently) possible if and only if n > 3t. To overcome this severe limitation, Pease et al. introduced a variant of BGP, Authenticated Byzantine General (ABG). Here play...
