Analytical model for performability evaluation of Practical Byzantine Fault-Tolerant systems
Expert Systems with Applications, 2023 Designing systems tolerant to faults is crucial to assure continuity of service for mission critical applications. However, their implementation may be costly and challenging. In this study, analytical models are presented for performance evaluation of systems equipped with Practical Byzantine Fault-Tolerant consensus protocols.

Practical framework for Byzantine fault-tolerant systems
, 2014 A distributed system executes one program or algorithm on multiple networked nodes. As computer network systems continue growing, it becomes increasingly complex to maintain their robustness. Some of the issues that have to be dealt with in a network are: subverted systems following an adversarial attack, unreliable transmission of data, as well as ...
