Efficient stream authentication in secure wireless multimedia space networks: The source-authentication-protocol optimality

Resource constrained secure deep space Inter-Planetary Multimedia Networks (IPMNs) gathering various planetary sensor information have high requirements for energy-efficient transmission, error-resilient multimedia coding and robust content authentication. However, the joint exploration of Intra-Inter video coding versatility in signal processing domain, Signature-Hash diversity in information security domain and Forward Channel Correction (FEC) channel coding application in network protocol domain has largely been ignored in literature. In this paper, we propose a new Source-Authentication-Protocol (SAP) framework to provide multimedia service quality, communication overhead efficiency and multimedia content integrity simultaneously. To provide robust video authentication while keeping bandwidth resource constraints, a novel SAP based network resource allocation scheme is proposed to improve energy efficiency and communication resource utilization in IPMN by jointly exploring the diversities in the source, the authentication and the protocol categories. Results based on simulation studies demonstrate the effectiveness of the proposed SAP scheme in achieving resource efficiency, video quality and authentication robustness, simultaneously.
