文中提出一种基于M序列的叛逆追踪方案。在该方案中,当发现盗版的解密盒时,能够以黑盒子的追踪方式至少追踪到一个制造盗版解密盒的用户(称为叛徒)。该方案的一个非常重要的特点是:当发现盗版的解密盒时,追踪的次数是与用户个数之间成线性关系的。因此,追踪算法的效率非常高。此外,追踪算法的实现不受共谋用户个数的限制。 In this paper, a recursive tracing scheme based on M sequence is proposed. In this scenario, when a pirated decryption box is found, it is possible to track at least one user (known as a traitor) who made the pirate decryption box in a black box tracking manner. A very important feature of this solution is that when a pirated decryption box is found, the number of traces is linear with the number of users. Therefore, the tracking algorithm is very efficient. In addition, the tracking algorithm is not limited to the number of conspirators.
