Abstract

The invention provides a method for preventing set top box software from malicious upgrade, comprising the steps as follows: step 10, encapsulating upgrade data by adopting RSA asymmetric cryptographic algorithm via a front end and transmitting the encapsulated data to a set top box; step 20, authenticating data received by the set top box, and entering a step 30 if the authentication is successful; otherwise, quitting the upgrade; step 30, analyzing the data received by the set top box to obtain upgrade data and performing upgrade according to the upgrade data. The invention further provides a system for preventing set top box software from malicious upgrade, comprising a data encapsulation module, an authentication module and an upgrade module. The method and the system of the invention improve safety of data and effectively prevent illegal operation.

Description

technical field

[0001] The invention relates to the field of communication technology, in particular to a method and system for preventing malicious upgrade of set-top box software. Background technique

[0002] At this stage, set-top box software upgrades are generally implemented through online over-the-air upgrades (OTA), USB upgrades, or serial port upgrades. From the header control information of the received upgrade data, the manufacturer ID, hardware version, and software version are analyzed. And compare it with the information of the running software of the current set-top box, and perform the upgrade operation if the comparison is successful, otherwise the upgrade cannot be completed. Due to the low confidentiality of information such as manufacturer ID, hardware version, and software version, it is easy to leak, and it is easy to cause an illegally generated malicious program to upgrade and destroy all set-top box software in operation.
