Abstract

The invention relates to the field of digital set top boxes, and provides an authorization system and method based on set top box card-free CA. The authorization system and method based on set top box card-free CA are used for solving the problem that a user cannot be authorized in the set top box card-free CA process. The authorization system comprises an initialization module, a cured ID reading module, a verification module and an authorization module. The initialization module is used for initialization of a set top box Flash memory. The cured ID reading module is used for reading the cured ID of the Flash memory. The verification module is used for verifying the cured ID. Whether the cured ID is the same as the cured ID, customized before delivery by an operator, of the Flash memory is judged according to the verification result, and if yes, the user is authorized. The chip ID of a master chip of a set top box is not used as an authorization certificate, so that the authorization system and method have the wider application range.

Description

technical field [0001] The invention relates to the field of digital set-top boxes, in particular to an authorization system and method based on a set-top box cardless CA. Background technique [0002] Conditional Access (CA) system is a digital payment system that encrypts digital TV programs to establish an effective charging system. It uses various digital technologies to encrypt programs so that operators can Only authorized users can watch encrypted programs, thus protecting the interests of operators and authorized users. At present, the conditional access methods used by domestic cable digital TV are mainly divided into two types based on the terminal receiving method: the first is the smart card method, which is characterized in that the decryption task is jointly completed by the smart card and the set-top box host chip; the second is The machine-card separation method is characterized in that the decryption is completed by the smart card alone. If the smart card ...
