WebThis is the first known solution that achieves optimal accuracy—the accuracy of synchronized clocks (with respect to real time) is as good as that specified for the underlying hardware clocks. We present a simple, efficient, and unified solution to the problems of synchronizing, initializing, and integrating clocks for systems with different … WebThis paper proposes the integration of internal and external clock synchronization by a combination of a fault-tolerant distributed algorithm for clock state correction with a central algorithm for clock rate correction. By means of hardware and simulation experiments it is shown that this combination improves the precision of the global time base in a … WebOct 27, 2024 · Cryptographic signatures can be used to increase the resilience of distributed systems against adversarial attacks, by increasing the number of faulty parties that can be tolerated.

WebAbstract. Reference-Broadcast Synchronization (RBS) is a technique that allows a set of receivers in a broadcast network to accurately estimate each others’ clock values. RBS provides a relative time-frame for conversion between the local clocks of different nodes, and can be used to synchronize nodes to an external time-source such as GPS.
