Abstract
A method is provided of generating and distributing secret random data. The method requires a plurality of participating parties each to own an identical private-key generation device and to request a random signal over a shared publication communication network. At each iteration of the method, the parties process the public random signal with the internal states of their secret-key generation devices using two functions, the output of the first function being generated secret random data and the output of the second function being a new internal state.
