Abstract
A method and system for authenticating computer nodes on a network, including providing a synchronized clock system, at a predetermined clock frequency, for use with an electronic system with a plurality of system nodes. Matching counters are connected to each of the plurality of system nodes, each of the counters being incremented in accordance with the clock frequency experienced by the system nodes to which the counters are connected. A difference is calculated between a count number at the end of a certain interval and the count number for the same counter at the beginning of the interval, to arrive at a count difference for each counter. The count difference of a particular counter is compared with the count difference of at least two other counters and, in the event that the count difference of the particular counter does not match, that node is noticed as an imposter.
