Secure Variable Data Rate Transmission

A novel secure variable data rate (SVDR) transmission method is presented along with an architecture for implementing the SVDR transmission. This method reduces transmission overhead requirements by allowing both parties to maintain the initialization vector information locally rather than by obtaining it from the received packet. The only requirement this method places on the transmission is to maintain the sequence. This brief shows a 70% reduction in the overhead for transmitting this sequence information with a window size of 10 and seven priority levels.
