Abstract
With the current channel limitations of Cellular Digital Packet Data (CDPD) networks and also the lack of bilateral authentication it is difficult to meet the bandwidth needs of secure real-time video. Various error sources make it difficult to meet the quality of service requirement within an acceptable bit error rate and delay. Access point limitations and additional security measures add more traffic overhead. Adaptive control over the network traffic provides extra support for end-to-end QoS. Thus adaptive multimedia applications are at the core of wireless media streaming [8]. In this paper we first show that CDPD is suitable for real-time video streaming by use of the adaptive Mediator System [7]. Then we provide an end-to-end encryption and bilateral authentication technique based on X.509 certificate between the mobile units and base stations. The overhead traffic resulting from the additional encryption and authentication layer is one of the major challenges for secure real-time video transmission over CDPD.
