摘要

基于类ElGamal加密体制

本文提出了一种无第三方参与的匿名数字指纹方案.在无第三方参与的情况下

该方案巧妙实现了销售商对匿名用户的身份认证

确保了只有合法注册用户才能得到数字产品;同时

销售商在收缴到盗版拷贝时

无须用户的参与就能够追踪出真正的盗版者.此外

方案还具备不可联系性

防诬陷性.方案的安全是基于解离散对数为困难问题.

Abstract

Based on the cryptosystem of ElGamal-like

this paper presents a new anonymous fingerprinting scheme without third party.Without involving any third party

this scheme helps merchants to verify the identity of anonymous buyers in order that only buyers registered can get the digital product.At the same time

merchants can trace back to the real pirate from a confiscated illegal copy without the buyer’s participation.Moreover

this scheme has the properties of unlinkable and frame-proofing.The safety of this scheme is based on the intractable problem of solving Discrete Logarithm.
