Abstract

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 voice 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, constructing (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 includes the creation (235) (or break down (270)) of a secure voice frame.
