Meteor Time Transfer and Meteor Cryptography

2007 IEEE International Frequency Control Symposium Joint with the 21st European Frequency and Time Forum, 2007
We show that peculiar properties of meteor wave propagation allow construction of radio channel that may deliver transfer of data with theoretically perfect protection from eavesdropping. Method uses natural stochastic process that is generated only for two communicating participants so that it is not available for possible cryptanalysis.
