METHODS AND APPARATUS FOR TRANSMITTING, RECEIVING, AND PROCESSING SECURE VOICE OVER INTERNET PROTOCOL

摘要

This disclosure describes systems and methods for processing voice data (110 , 150) for secure transmission and secure receipt over a network, such as the Internet (250). The systems and methods include the processing of analog voi ce and digital information, including conversion of a voice signal into digital information (215) (or of digital information into a voice signal (290)) and transmission (240) (or receipt (265)) of digital information representing voice data over a network (250). The analog-to-digital conversion (215) (and digital-to-analog conversion (290)) is followed by coding (220) (or decoding (285)) digital information according to voice coding techniques, constructin g (225) (or deconstructing (280)) a voice frame, and encrypting (230) (or decrypting (275)) digital information according to the encryption techniques . The transmission (240) (or receival (265)) of the digital information includ es the creation (235) (or break down (270)) of a secure voice frame.
