DATA ENCRYPTION STANDARD USING TMS32010 (CONTAINS SCANNED TEXT)

This report examines the implementation of a data encryption method using the TMS32010. The encryption algorithm chosen for the report is the Data Encryption Standard (DES). This report details the DES algorithm and its TMS32010 coding. Processor resource requirements are also provided for applying the DES to speech coding at different bit rates. For a 2.4kbit/s LPC vocoder application, the DES only requires six percent of the TMS32010 CPU loading. The encryption scheme operates on a stream of bits that represent text, computer files, speech, or any other entity in binary form. The result is directly applicable to the design of any secure data/voice communications.
