Optimal clock synchronization with signatures

Webbound of 1. The second essential aspect of clock synchronization is how clock drifts are modeled. Typically, it is assumed that each node has a hardware clock with a bounded drift. A common way to model the clock drift is to de ne that all hardware clock rates are always in the interval [1 ˆ;1 + ˆ] for a constant ˆ2(0;1). WebJul 25, 1995 · Abstract. We propose an optimal convergence function for achieving fault-tolerant, internal clock synchronization in the presence of arbitrary process and clock …

WebEach node uses its hardware clock and messages it receives from other nodes to compute a logical clock value. 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 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 … Webfault-tolerant clock synchronization, even in fully connected systems.

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.
