Are bosonic replicas faulty?

چکیده

Motivated by the ongoing discussion about a seeming asymmetry in the performance of fermionic and bosonic replicas, we present an exact, nonperturbative approach to both fermionic and bosonic zero-dimensional replica field theories belonging to the broadly interpreted beta=2 Dyson symmetry class. We then utilize the formalism developed to demonstrate that the bosonic replicas do correctly reproduce the microscopic spectral density in the QCD-inspired chiral Gaussian unitary ensemble. This disproves the myth that the bosonic replica field theories are intrinsically faulty.

Byzantine Fault Tolerance in Long-Lived Systems

Byzantine fault tolerance comprises a set of techniques for building fault-tolerant systems where no assumptions are made about the behavior of faulty nodes. This makes Byzantine-fault-tolerant systems particularly attractive as a defense against malicious attacks that may cause faulty nodes to exhibit arbitrary behavior. A service that tolerates Byzantine failures (e.g., [1, 8]) must store the...

DIVERSYS: DIVErse Rejuvenation SYStem

Replication has been used to build intrusion-tolerant systems, which are able to tolerate a limited number intrusions before the system is compromised. An important limitation of intrusion-tolerant systems is that if the system’s replicas are similar, once a flaw is discovered and exploited in one replica, then it is easy to replicate it on the other replicas, compromising the whole system. To ...

Diffusion without false rumors: on propagating updates in a Byzantine environment

We study how to efficiently diffuse updates to a large distributed system of data replicas, some of which may exhibit arbitrary (Byzantine) failures. We assume that strictly fewer than t replicas fail, and that each update is initially received by at least t correct replicas. The goal is to diffuse each update to all correct replicas while ensuring that correct replicas accept no updates genera...

Failure Resilient Distributed Commit for Web Services Atomic Transactions

Existing Byzantine fault tolerant distributed commit algorithms are resilient to failures up to the threshold imposed by the Byzantine agreement. A distributed transaction might not commit atomically at correct participants if there are more faults. In this paper, we report mechanisms and their implementations in the context of a Web services atomic transaction framework that significantly incr...

Practical Byzantine Fault Tolerance Using Fewer than 3f+1 Active Replicas

Byzantine fault tolerant state machine replication (BFT-SMR) is a foundation for implementations of highly reliable services. Existing algorithms for BFT-SMR require at least 3f +1 active replicas to tolerate f faulty replicas. We show that BFT-SMR can be achieved with fewer than 3f +1 active replicas, as long as standby spare replicas are available, such that the number of active replicas plus...
