Abstract
A method for encrypting an information carrier comprising generating a sequence of data using a sequence generator, modulating, using a first modulator an output from the sequence generator such that an interference signal results, encoding the interference generator's synchronization information using an encoder, modulating, using a second modulator, the encoded synchronization information such that a synchronization carrier signal results, spreading the synchronization carrier signal using a spreader such that a spread sub-carrier synchronization signal results, and combining the modulated information carrier signal, interference signal, and spread sub-carrier synchronization signal using a signal combiner such that a composite signal results, the interference signal having one or more signal characteristics that results in obfuscation of the information carrier signal when the information carrier signal and interference signal are combined.
