摘要
基于离散对数困难问题提出了一种新的容忍入侵的基于代理的叛徒追踪方案,详细地分析了方案的完备性和安全性。该方案能够在数据内容提供商及单个或多个代理不可信的情况下保证合法授权用户的安全性。
A new intrusion-tolerant agent based traitor tracing scheme based on the assumption that solving the discrete logarithm problem is presented, and the completeness and security analysis of the scheme is given in detail. The proposed scheme ensures the security of the legal authorized users in the case of that the digital providers and one or more agents are not trusted.
