适合概率隐私同态的买方－卖方水印协议
Buyer-seller watermarking protocols suitable for probabilistic privacy homomorphisms
最近提出的一些水印协议有一个共同的缺陷,就是方案中只能使用确定性隐私同态加密算法,它导致了水印的安全性和鲁棒性之间一个不可回避的矛盾。本文对两个重要的买方－卖方水印协议进行改进,使之能够适合概率性隐私同态加密算法,从而去除这个缺陷。另外改进后的协议能够很好的解决原协议中存在的安全验证问题。
common limitation of some recently proposed watermarking protocols lies in the requirement of deterministic privacy homomorphisms which would result in an inevitable contradiction between the security and the robustness of watermarks. The present paper provides afix to two important buyer-seller watermarking protocols by removingthis limitation. In addition, the improved protocols solve thesecure verification problem existing in the original ones.
