Problems solved by technology

[0004] Existing set-top boxes directly store these executable applications in the external memory of the set-top box, so it is easy to be decompiled and cracked by hackers after reading directly from the external memory.
The cracked update program provided by the hacker can bypass some simple inspection mechanisms of the manufacturer, illegally use some paid services of the manufacturer, and damage the legitimate commercial interests of the manufacturer

Abstract

The invention discloses a STB (set top box) application downloading method and an STB. The STB application downloading method comprises the following steps: an application downloading operation of a user is responded, and a public key is read in an OTP (one time programmable) area of one-time writing equipment; the public key is used for decryption of a reserved part of the application; the application after decryption is checked; and the application is operated according to a pre-set procedure after checking succeeds. STB applications can be downloaded more safely with the method.

Description

technical field [0001] The invention relates to the technical field of electronic security, in particular to a method for downloading an application program of a set-top box and the set-top box. Background technique [0002] With the widespread promotion of digital TV, set-top boxes have been widely used, and users can watch more and more TV programs and some special channels through the set-top boxes. [0003] Some services provided by the set-top box to users are charged, such as some special channels or some foreign TV programs, which can only be provided to users who pay. These application programs are all stored in the external memory of the set-top box, and these charging items can be used by processing the information of the set-top box such as program upgrades. [0004] Existing set-top boxes directly store these executable application programs in the external memory of the set-top box, so it is easy to be decompiled and cracked after being read directly from the ex...
