NeTS:Small: A Joint Layered Coding Scheme for Unified Reliable and Secure Media Transmission over Wireless Networks

本研究的目的是开发一种联合分层编码方案，以满足无线网络端到端同步错误保护和安全媒体传输的需要。该方法利用了JPEG2000和MPEG-4/H.264等媒体编码标准压缩的数字媒体分层结构。同时保护错误和身份验证是这个项目的一个重要目标。本研究的智力优势在于对认证策略和数据单元选择的综合研究；联合介质错误和认证保护；并对媒体传输系统的各个组成部分进行最优的速率分配。提出的联合分层编码方案有可能在同一框架内实现错误保护和身份验证的设计，并实现最优的资源和带宽分配。关于更广泛的影响，这里研究的集成原则有可能被应用到更一般的系统设计中，其中组件竞争有限的资源。此外，基于分层编码的集成媒体身份验证方案具有抵御拒绝服务攻击的潜力，从而解决了重要的安全需求。通过与纽约州立大学布法罗分校信息保障研究与教育卓越中心合作，该项目为本科生提供了动手培训的机会。

The objective of this research is to develop a joint layered coding scheme to meet the needs of end-to-end simultaneous error protection and secure media transmission over wireless networks. The approach takes advantage of the hierarchical structure of digital media compressed by media coding standards, such as JPEG2000 and MPEG-4/H.264. Simultaneous error and authentication protection is a significant goal of this project.The intellectual merit of this research lies in the integrated investigations into authentication strategy and data unit selection; joint media error and authentication protection; and optimal rate allocation for all components of the media transmission system. The proposed joint layered coding scheme has the potential to enable the design of both error protection and authentication within the same framework and to achieve optimal resource and bandwidth allocation.With respect to broader impact, the integration principle investigated here has the potential to be applied to more general system designs where components are competing for limited resources. Also, the layered coding-based integrated media authentication scheme has the potential to be resilient to denial-of-service attacks, thus addressing an important security need. By working with the Center of Excellence in Information Assurance Research and Education at SUNY at Buffalo, this project provides undergraduate students with hands-on training opportunities.
