The present invention discloses a kind of a digital TV conditional access system and related handling procedure. Hayeotneun solve the defects of the prior art conditional access television safety, production cost, currency onto the bar system, manufacturing cost was high safety is low has the advantage the strong currency. The structure includes an authentication module, a conditional access front-end module, the receiving module. The authentication module and the receiving module, and is of the two-way communication, the receiver forms a unique ID number and authentication information, the authentication proceeds to the reception module, and registers the information of the reception module in the database. The conditional access front end module and a database with two-way communication, and complete the encryption process for the entitlement management message belonging to the same receiving terminal fetches the receiving end information on the database, through a corresponding one addressing transmitted to the receiving module, a conditional access front- -end module includes a corresponding one entitlement control message generator. Receiving module by using the authentication information and the ID number generated during the authentication process, thus completing the safety limitations of the scrambled program received.
