Authentication in a reconfigurable Byzantine fault tolerant system
Byzantine (i.e. arbitrary) faults occur as a result of software errors and malicious attacks; they are increasingly a problem as people come to depend more and more on online services. Systems that provide critical services must behave correctly in the face of Byzantine faults. Correct service in …

Wireless reconfigurability of fault-tolerant processing systems
… buses for communication in a real-time computer system designed for applications with high reliability requirements. This work is based on the Draper Laboratory Software Based Redundancy Management System (SBRMS), which is a fault-tolerant system architecture that uses data exchange and voting …

The design of a real time, fault-tolerant, multiprocessor system.
… The majority of methods used to achieve fault tolerance in such systems employ a substantial duplication of hardware. This thesis suggests an alternative approach by placing a greater emphasis on firmware. It is shown that a greater degree of control can be obtained in a microprogrammed …

Authentication Based on Blockchain
… at cheap cost with elastic and scalable, fault tolerant system. These online services are offered by services providers which are use authentication, authorization and accounting framework based on client-server model. Though this model has been used over decades, study shows it is …

Black-Box Fuzzing of the REDHAWK Software Communications Architecture
… a methodology that acts only on the inputs of a system and iteratively generates new test cases in order to identify points of failure in the system under test. The REDHAWK implementation of the Software Communications Architecture is employed as the system under test by a fuzzing framework …

Coding approaches to fault tolerance in dynamic systems
A fault-tolerant system tolerates internal failures while preserving desirable overall behavior. Fault tolerance is necessary in life-critical or inaccessible applications, and also enables the design of reliable systems out of unreliable, less expensive components. This thesis discusses fault …

Fault tolerant strategy for actively controlled railway wheelset
… passive suspension raises the issue of the system safety in the event of a failure of the active control, which could result in the loss of stability and in more severe cases, derailment. Further on, in active control systems for railway vehicles the actuators tend to be significantly more …

A Performance-Efficient and Practical Processor Error Recovery Framework
… processor. Permanent transistor breakdown, or faults, can occur at any point in time in the processor’s lifetime. Errors are the discrepancies in the output of faulty circuits. This dissertation shows that the components containing faults can continue operating if the errors caused by them are …

Advanced I/O Techniques for Efficient and Highly Available Process Crash Recovery Protocols
… grow, the availability and reliability of these systems become a primary concern. As such, some solutions are physical (ie. power backup) and some are software driven. Lawrence Berkeley National Laboratory has created a system-level fault-tolerant checkpoint/restart implementation for Linux …

AI-driven methods for resiliency and security assessment: the case for autonomous driving system and HPC storage system
Nowadays, computing systems are used extensively in mission-critical exploration, transportation, scientific study, and manufacturing. With the advances in computation technologies, computing systems have become ever more complex. Due to the system’s complexity, it is increasingly hard for humans …
