Abstract:
1. A distributed revocation method comprising: conducting a vote amongst at least three autonomous device nodes of a distributed network regarding whether a suspect autonomous device node of the distributed network should be removed from the distributed network; responsive to said vote satisfying a revocation criterion, ceasing communication between the suspect autonomous device node and the other autonomous device nodes of the distributed network by (i) constructing a revocation message by combining partial revocation information for revoking the suspect autonomous device node that is distributed amongst at least some of the autonomous device nodes of the distributed network other than the suspect autonomous device node, and (ii) transmitting the revocation message amongst the autonomous device nodes over the distributed network; and authenticating the revocation message by comparing a first portion of the revocation message processed by a one-way function with a second portion of the revocation message.
