摘要: 针对目前数字版权保护协议中第三方负担过重的缺陷,提出一种简洁、高效、安全的保护买、卖方权益的数字水印协议及其模型。该协议通过内容服务器产生数字水印池和移动代理动态分发许可证这两种机制,解决了共谋容限性、中间人攻击、硬盘克隆攻击和用户叛逆等安全问题。并通过加密、认证、数字签名和单向置换函数有效地保证了协议中实体交互数据的安全性和完整性。另外,还采用买方脱离仲裁的机制,使得协议更为完善、可行。

Abstract: Concerning the overburdened third party problem of the present digital copyright protection protocol, this paper put forward a simple, efficient, secure copyright protection protocol and model to protect the buyer and seller's interests. Through two mechanisms of content server generating digital watermarking pool and mobile Agent dynamic distributing license, the protocol solved the security problems such as tolerance of conspiracy, middle attacks, hard disk cloning attacks and user treason. And it ensured the data security and integrity in the protocol entities exchange through encryption, authentication, digital signature and one-way permutation function. In addition, it still adopted the mechanism of buyer from arbitration, which enabled protocol more perfect and feasible.

Key words: copyright protection, watermarking protocol, digital watermarking pool, conspiracy tolerance, hard disk clone
