CAREER: Integrated Coding and Content Delivery for Secure Media Streaming on P2P Networks

在她的研究计划中，首席研究员(PI)建议对P2P网络上的多媒体编码、内容分发和安全进行综合研究。IP网络上的媒体流媒体一直受到带宽有限、端到端延迟大且变化大以及播放质量差的限制。P2P网络的出现为流媒体带来了新的机遇(例如，来自参与节点的更多带宽和由于路径多样性而产生的更低的延迟)，也给流媒体带来了新的挑战(例如，安全风险)。该项目旨在充分利用多媒体编码的交互作用、编码码流的结构、覆盖网络体系结构和传输策略来充分发挥P2P网络在媒体流媒体中的潜力，与P2P网络相关的安全问题意味着我们需要为此类网络上的媒体流媒体提供安全服务(如密码和认证)。然而，安全和服务质量有时会提出相互冲突的要求。在这个项目中，PI将深入研究它们之间的关系和权衡，并研究如何利用P2P网络体系结构来缓解安全和Qos要求之间的紧张关系。在她的教育计划中，PI努力通过将最新研究进展融入到教学活动中来拓宽教育范围，提高教育质量。该计划由三部分组成：1)利用与当地工业和研究实验室的联系，让学生了解最新的技术和创新；2)通过课程开发加强本科生和研究生课程；3)让代表不足的群体的学生参与研究项目。智力优势。PI研究计划将导致媒体流应用程序具有更高的服务质量和更好的防止恶意攻击的保护。虽然之前的工作考察了P2P流媒体体系结构、媒体交付和内容保护的各个方面，但本项目提出的研究任务是以一种综合的方式研究服务质量和安全问题，利用网络、信号处理和安全社区的新发展。PI认为，这种综合方法更有可能推动通用多媒体网络应用在服务质量和安全方面的最先进技术。拟议的职业发展计划将在多个方面广泛影响大学、工业和研究社区。1)它创建并促进了与硅谷当地行业的协同关系；2)它加强了圣何塞州立大学计算机工程系的本科生和研究生课程，圣何塞州立大学是一所非博士授予机构；3)它接触到本科生、少数族裔和女性学生，让他们参与具有挑战性的研究项目；4)它通过公开项目结果来帮助研究和教育界。研究成果将以文章形式发表，相关软件和课程材料将在网上提供。

In her research plan, the principal investigator (PI) proposes to carry out integrated research on multimedia coding, content delivery, and security for media streaming on Peer-to-Peer (P2P) networks.Media streaming on IP networks has been constrained by limited bandwidth, large and variant end-to-end delay, and poor playback quality. The advent of P2P networks brought new opportunities (e.g., more bandwidth from participating peers and lower delay because of path diversity) and new challenges (e.g., security risk) for media streaming. This project aims to realize the full potential of P2P networks in media streaming by exploiting the interaction of multimedia coding, the structure of coded bit stream, overlay network architecture, and transmission strategies.Security issues associated with P2P networks imply that we need to provide security services (e.g., cryptography and authentication) for media streaming on such networks. However, security and QoS sometimes raise conflicting requirements. In this project, the PI will thoroughly study their relationship and tradeoff, and investigate how to leverage P2P network architecture to ease the tension between security and QoS requirements.In her education plan, the PI endeavors to broaden the scope and improve the quality of education by integrating the latest research developments into instructional activities. The plan consists of three components: 1) exploiting ties with local industry and research labs to keep students up-to-date with new technologies and innovations; 2) enhancing both undergraduate and graduate courses in networking through curriculum development; and 3) involving students from underrepresented groups in research projects.Intellectual Merit. The PIs research plan will lead to media streaming applications with improved QoS and better protection from malicious attacks. While previous work inspected individual aspects on P2P media streaming architecture, media delivery, and content protection, the proposed research tasks in this project study QoS and security issues in an integrated fashion, exploiting new developments in the networking, signal processing, and security communities. The PI believes that this integrated approach is more likely to advance the state-of-the-art technology in QoS and security for general multimedia networking applications.Broader Impacts. The proposed career development plan will broadly impact the university, industry and research community in a number of ways. 1) It creates and fosters a synergistic relationship with local industry in Silicon Valley; 2) It enhances both undergraduate and graduate curriculum in the Computer Engineering Department, San Jose State University, a non-Ph.D. granting institution; 3) It reaches out to undergraduate, minority, and women students to involve them in challenging research projects; 4) It helps the research and educational community by making project results publicly available. The research results will be published in articles, while related software and course materials will be made available on the web.
