Abstract :
A digital certificate scheme in content protection system for high definition digital interfaces is proposed. Before transferring the encryption content, the device interface is firstly confirmed whether it is passed the certification. After the certification, then transfers the content. The interface of the receiver detects whether the recognition management unit has passed the certification. The digital content is ensured by the recognition management unit, which can prevent the invalid capturing the information. In the period of certification, the characteristics of the certificate are fully made use of. the application shows the system is high secure, which can be used in the high definition digital interface.
