【摘要】 将会话密钥S分解成S1与S2之和。在大整数分解困难问题的条件下,构造特殊多项式函数来解密S1(方案1)。在离散对数困难问题的条件下,利用中国剩余定理来解密S2(方案2)。在两种方案组合的基础上形成一种新的叛逆者追踪方案。新方案兼有前两种方案的共同优点,同时弥补了它们各自的不足。新方案具有抗共谋性、非对称性、用户密钥的耐用性、黑盒子追踪等优越特性。更多还原

【Abstract】 The session key S is divided into a sum of S₁ and S₂. Under the condition of large integer factoring problem, S₁ is decrypted by constructing a special polynomial function（scheme 1）. Under the condition of discrete logarithm problem, S₂ is decrypted by Chinese Remainder Theorem（scheme 2）.On the basis of a combination of the scheme 1 and scheme 2, a new traitor tracing scheme is formed, which has both advantages of them, meanwhile overcomes their disadvantages. It has many advantages such as collusion-resistance, asymmetry, long-lived subscriber’s key, and black-box tracing.更多还原
