Introducing a Novel Data over
Voice Technique for Secure Voice
Communication
Piotr Krasnowski, Bruno Martin, Jerome Lebrun
The current increasingneedforprivacy-preservingvoice communicationsisleadingtonew ideasfor
securingvoice transmission. Thispaperreferstoarelativelynew conceptof sendingencrypteddataor
speechaspseudo-speechinthe audiodomainoverexistingvoice communicationinfrastructures,like3G
cellularnetworkandVoice overIP(VoIP).The distinctive characteristicof sucha communicationsystemis
that itreliesonthe robusttransmissionof binaryinformationinthe formof audiosignal.
Thiswork presentsanovel DataoverVoice (DoV) technique basedoncodebooksof shortharmonic
waveforms.The technique providesasufficientlyfastandreliable datarate overcellularnetworksand
manyVoIPapplications.The newmethodreliesongeneral principlesof LinearPredictiveCodingforvoice
compression(LPCvoice coding) andismore versatilecomparedtosolutionstrained onexactchannel
models.The techniquegivesbydesignahighcontrol overthe desiredrate of transmissionandprovides
robustnesstochannel distortion.Inaddition,anefficientcodebookdesignapproachinspiredby
quaternaryerrorcorrectingcodesis proposed.
The usabilityof the proposedDoV techniqueforsecure voice communicationovercellularnetworksand
VoIPhasbeensuccessfullyvalidatedbyempirical experiments.The paperdetailsthe systemparameters,
