Optimal clock synchronization with signatures
WebJan 1, 2014 · Two conditions must be satisfied to achieve high-precision clock synchronization: high resolution timers and optimal clock synchronization algorithm. Clock resolution is determined by the physical characteristics of the hardware, so this paper only does research on algorithms. ... These models are then used as signature function to … WebCryptographic 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. While this is well-studied for consensus, it has been underexplored in the context of fault-tolerant clock synchronization, even in fully connected systems. Here, the honest parties …

Denote the value of node i’s logical clock at time t by Li(t). The clock synchronization algorithm tries to ensure that the logical clock values of the nodes are close to each other, and close to real time. 4.2 Communication Network

WebNov 24, 2024 · The timer has automatically timed these paths as synchronous. In order to constrain asynchronous clock domain crossings correctly, there are four things to consider: If there are no paths between the two clocks, the simply use set_clock_groups or set_false_path between the two clocks. If the paths are all single big CDCs then you can … 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.
