AbstractLee-Chang-Lin-Hwang in 2000 proposed a set of protocols for Pay-TV systems in order to secure subscriber's privacy and build a fair Pay-TV system. However, we have found that an attacker can easily get other subscriber's privacy in watching TV-programs. We analyze the reason and discuss the possible amendments. Moreover, we expose a weakness on non-repudiation and suggest an improvement to support non-repudiation.
