| 摘 要： | 多播、水印、指纹的结合是多播安全的一个重要方面，相关的协议设计具有一定的难度．多播具有明显的高性能优势，水印通过在数字产品中嵌入版权所有者信息提供版权保护，指纹通过识别泄漏者提供版权保护，Chu提出了一个多播水印协议MWP，但没有研究如何进行指纹编码，因此在识别泄漏者、抵御合谋攻击方面缺乏理论依据，并且从实践的角度看，在原始数据量较小的情况下，MWP不能识别泄漏者，也不能抵御合谋攻击，鉴于此，本文基于指纹码的理论和方法以及数据分割方案，改进了MWP协议，改进后的协议在原始数据量较小的情况下也能够有效地识别泄露者、抵御合谋攻击。

| Abstract: | The integration of multicast, digital watermarking and digital fingerprinting is an important aspect of multicast security, the related protocol design is difficult. Multicast take the advantage of high performance, digital watermarking provide with copyright protection by embedding the owner information in digital products, digital fingerprinting provide with copyright protection by identifying the leakers or traitors. Chu presented a Multicast Watermark Protocol (MWP), however, did not provide the schemes by which the fingerprint can be coded, so from the theoretical point of view, there does not exist the foundation for leaker identification and being collusion free, Furthermore, from the practical point of view, MWP cannot identify the leaker and be collusion free in the case of smaller amount of raw data. This paper improves the MWP protocol based on digital fingerprinting theories, approaches and data segmentation schemes,the improved protocol can identify the leaker and be collusion free in the case of smaller amount of raw data. |
