Abstract: Traitor tracing schemes are a very useful tool for preventing piracy in digital content distribution systems. By applying oblivious polynomial evaluation and bilinear map, we propose an asymmetric traitor tracing scheme. Compared with the existing schemes based on bilinear map, the scheme has the property of non-repudiation.

Key words: non-repudiation, oblivious polynomial evaluation, bilinear map, traitor tracing, asymmetric

摘要: 在数字产品销售中,叛逆者追踪方案是防止盗版的非常有用的工具。利用不经意多项式估值协议和双线性映射提出了一种非对称的叛逆者追踪方案,与现有的基于双线性映射的方案相比,该方案具有不可否认性。
