Synchronization of Fault-Tolerant Clocks in the Presence of Malicious Failures
April 1988 (vol. 37 no. 4)
pp. 440-448
The problem of achieving global clock synchronization in fault-tolerant clocks by preventing so-called multiple cliques in the presence of malicious clock failures (i.e. clock failures that are perceived differently by different nonfaulty clocks) is addressed. A solution to the problem, referred to as the averaging rule, is developed, and its use is analytically justified using the notions of c
