Embodiment Construction

[0021] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0022] In the present invention, whether the communication link between the CPU of the set-top box and the encryption device is set through the result of verifying the user information is turned on or not, and when it is turned on, the internal software of the set-top box is encrypted and protected by the encryption device, combined with software, The hardware encryption method is more secure, reliable and stable than the pure software encryption method.

[0023] figure 1 The implementation process of the encryption protection method of the set-top box software provided by the present invention is...

Abstract

The invention provides a set-top box software encipherment protection method and system and a set-top box, which are suitable for the field of digital televisions. The set-top box software encipherment protection method comprises the following steps: obtaining and certifying user information, if the user information passes the certification, a communication link between the CPU and the encryption equipment of the set-top box is on, and if the user information can not pass the certification, the communication link between the CPU and the encryption equipment of the set-top box is off; utilizing the encryption equipment to carry out encipherment protection for the inner software of the set-top box when the communication link between the CPU and the encryption equipment of the set-top box is on. In the method, if the communication link between the CPU and the encryption equipment of the set-top box is on and off is determined by a certification result of the user information, the encryption equipment is utilized for the encipherment protection of the inner software of the set-top box when the communication link is on, and the method is safer and more reliable relative to an encryption mode of pure software by combining encryption modes of software and hardware so as to be more stable.

Description

technical field [0001] The invention belongs to the field of digital television, and in particular relates to an encryption protection method and system for set-top box software and the set-top box. Background technique [0002] With the popularization of digital TV, more and more families use digital TV. For most families, all they have are analog TV receivers. In order to cooperate with receiving digital TV, they need to use a set-top box. Because digital TV has many services, correspondingly, there are many application software in the set-top box. [0003] At present, the application software piracy of set-top boxes emerges in an endless stream. In order to protect the rights and interests of consumers and set-top box manufacturers, various encryption protection methods for set-top boxes have emerged. Common encryption protection methods include: network registration and license protection methods, but this method needs to be implemented with the help of the network, so...
