Secure and Efficient Voice-over-IP in a cdma2000 Network

This paper examines how to provide secure and efficient voice-over-IP service on a cdma2000(R) network. Various alternative solutions and their relationship to header compression techniques are discussed. We propose a new method of end-to-end encryption that could be used to provide privacy even when Header Removal, a cdma2000(r)-specific technique where IP/UDP/RTP headers are discarded before transmission over the air, is in use.
