Abstract

THE PRESENT INVENTION DISCLOSES A METHOD AND SYSTEM FOR PROVIDING OR ENSURING SYNCHRONIZATION OF CRYPTOGRAPHIC DEVICES FOR TRANSMISSION OF DATA WITHIN A VOICE CHANNEL, PARTICULARLY THE GSM VOICE CHANNEL NETWORK. THE TRANSMISSION SOURCE (100) IS CONFIGURED TO GENERATE SEVERAL CYCLES OF 32-BIT DIGITAL ZEROS DATA PRIOR TO TRANSMITTING THE ENCRYPTED DATA TO THE RECEPTION SOURCE (200). ACCORDINGLY, THE TRANSMISSION OF DIGITAL ZEROS DATA PROVIDES SUFFICIENT TIME FOR THE RECEPTION SOURCE (200) TO PREPARE FOR RECEIVING THE ENCRYPTED DATA FROM THE TRANSMISSION SOURCE (100) AND THEREBY ASSISTING IN SYNCHRONIZATION OF DEVICES INITIALIZATION FOR DATA TRANSMISSION.
