摘要： 利用RS 码和两锁密码协议构造了一种非对称的公钥叛逆者追踪方案。在方案中，数据发行商可以动态地废除叛逆者的解密能力。同时，利用此叛逆者追踪方案，构造出一种签发电子证书和软件安装方案，从而给出了一种有效的数字版权保护方案。

Abstract: By applying RS code and two-locks cipher protocol, this paper constructs an asymmetric public key traitor tracing scheme. In the scheme, the data supplier can dynamically revoke the traitor’s decryption ability. At the same time, using the traitor tracing scheme, it constructs a kind of signing electronic license and software installation scheme which gives an efficient digital copyright protection scheme
