摘要

基于P2P-CDN混合架构的视频点播(VoD)流媒体服务很好地平衡了CDN提供的高可靠性和P2P提供的高扩展性。然而，P2P网络的难以管理和不可信的特点会给版权所有者和用户带来内容盗版和安全威胁。到目前为止，文献中还没有一种充分的基于P2P- cdn提供点播流媒体服务的方案，在保证P2P流媒体性能效率的同时解决内容保护和安全交付问题。本文提出了一种可管理的、安全的P2P-CDN视频点播流传输方案，该方案将需求与区块链和零知识相结合。实验结果表明，即使在大规模的P2P网络下，与目前应用最广泛和最成熟的P2P- cdn系统相比，我们提出的方案在性能指标和安全性方面都能提供更好的视频点播流媒体服务。

Enabling Manageable and Secure Hybrid P2P-CDN Video-on-Demand Streaming Services Through Coordinating Blockchain and Zero Knowledge

Video-on-Demand (VoD) streaming services on the hybrid P2P-CDN architecture nicely balance the high reliability contributed by the CDN, and the great scalability provided by P2P. However, the unmanageable and trustless feature of the P2P network can cause content piracy and security threats to the copyright holders and users. To date, there has not been an adequate scheme based on P2P-CDN providing VoD streaming services in the literature that resolves the content protection and secure delivery while keeping up the efficiency of P2P streaming performance. In this work, a manageable and secure VoD streaming delivery scheme is proposed for P2P-CDN, which marries the requisite requirements with the blockchain and zero-knowledge. The experimental results show that our proposed scheme offers a superior VoD streaming service both on the performance metrics and security compared with the most widely used and mature system for P2P-CDN nowadays, even under a large-scale P2P network.

期刊介绍： The magazine contains technical information covering a broad range of issues in multimedia systems and applications. Articles discuss research as well as advanced practice in hardware/software and are expected to span the range from theory to working systems. Especially encouraged are papers discussing experiences with new or advanced systems and subsystems. To avoid unnecessary overlap with existing publications, acceptable papers must have a significant focus on aspects unique to multimedia systems and applications. These aspects are likely to be related to the special needs of multimedia information compared to other electronic data, for example, the size requirements of digital media and the importance of time in the representation of such media. The following list is not exhaustive, but is representative of the topics that are covered: Hardware and software for media compression, coding & processing; Media representations & standards for storage, editing, interchange, transmission & presentation; Hardware platforms supporting multimedia applications; Operating systems suitable for multimedia applications; Storage devices & technologies for multimedia information; Network technologies, protocols, architectures & delivery techniques intended for multimedia; Synchronization issues; Multimedia databases; Formalisms for multimedia information systems & applications; Programming paradigms & languages for multimedia; Multimedia user interfaces; Media creation integration editing & management; Creation & modification of multimedia applications.
