Problems solved by technology

But this method still has defect: this method is difficult to guarantee the uniqueness of the software that is burnt into the set-top box (that is, a box corresponds to a software), so that the function interface of the third-party software can be modified by using the disassembly technology, thereby normally reading the FLASH ( flash memory) and burn the software into other set-top boxes at will, so as to achieve the purpose of piracy

Abstract

The invention discloses a set-top box protection method and a set-top box. The method comprises the following steps of: acquiring a public key, wherein the public key is an identification code of the set-top box; decrypting encrypted codes of the set-top box by using the public key, wherein the encrypted codes are generated by encrypting the identification code of the set-top box and a code of the set-top box by a preset encryption algorithm; and judging whether the decrypted identification code is consistent with the public key or not, and if the decrypted identification code is judged to be inconsistent with the public key, quitting a system. The invention correspondingly provides a technical scheme of the set-top box. By the set-top box protection method, the uniqueness of software and hardware of the set-top box can be ensured, the set-top box can be protected from piracies, and the protection cost can be reduced.

Description

technical field [0001] The invention relates to the technical field of set-top boxes, in particular to a method for protecting a set-top box and the set-top box. Background technique [0002] At present, the set-top box technology is constantly developing, and users can enjoy more TV program services through the set-top box. The performance of the set-top boxes provided by major set-top box manufacturers is also continuously improved. However, there are also some bad phenomena in the application of set-top boxes today. For example, some users illegally crack the software or hardware of the set-top box and carry out pirated production to obtain illegal benefits, thus causing reputation and economic damage to the set-top box manufacturers and TV operators. on the loss. Therefore, the set-top box needs to be protected to prevent the software and hardware of the set-top box from being cracked and pirated. [0003] The method for protecting the set-top box in the prior art, fo...
