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.

本研究的目的是开发一种联合分层编码方案，以满足无线网络上端到端同时错误保护和安全媒体传输的需求。 该方法利用了由媒体编码标准（例如 JPEG2000 和 MPEG-4/H.264）压缩的数字媒体的分层结构。 同时错误和认证保护是该项目的一个重要目标。本研究的智力价值在于对认证策略和数据单元选择的综合研究；联合媒体错误和身份验证保护；以及媒体传输系统所有组件的最佳速率分配。 所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，并实现最佳的资源和带宽分配。就更广泛的影响而言，这里研究的集成原理有可能应用于组件竞争有限资源的更通用的系统设计。 此外，基于分层编码的集成媒体认证方案具有抵御拒绝服务攻击的潜力，从而满足重要的安全需求。 通过与纽约州立大学布法罗分校信息保障研究和教育卓越中心合作，该项目为本科生提供实践培训机会。
