Embodiment Construction

[0016] Such as figure 1 As shown, it is a schematic structural diagram of the system applying the set-top box software upgrading method of the present invention. The system includes: a set-top box 10 , a subscriber identity module (Subscriber Identity Module, SIM for short) 20 and an upgrade service device 30 .

[0017] Set-top box 10 is the equipment to be carried out software upgrade, when needing to carry out software upgrade, set-top box 10 sends the upgrade package download request that carries upgrade parameter to upgrade server 30, and upgrade parameter can comprise parameters such as the hardware version number of set-top box, operating system version number .

[0018] The upgrade server 30 stores the upgrade packages of various set-top boxes, and downloads the corresponding upgrade packages, upgrade package digests and encrypted digests obtained by encrypting the upgrade package digests to the set-top box 10 according to the upgrade parameters. Wherein, the upgrade ...

Abstract

This invention relates to an upgrading method and a system for software of set-top-boxe, in which, a set-top box transmits a downloading request of upgrading packet to an upgrading service device carrying with upgrading parameter of the set-top-box, which downloads the upgrading packet, abstract and ciphered abstract to the set-top box, which sends the ciphered abstract to a user identifying module to decode it according to stored cipher to get decoded result, the set-top-box installs the upgrading packet at the time when the abstract of the upgrading packet is the same with the de-ciphered result, which increases safety of software upgrading by verification of the upgrading packet and reduces possibility of being attacked to the set-top-box.

Description

technical field [0001] The invention relates to communication technology, in particular to a set-top box software upgrading method, an upgrading system, a set-top box, a user identification module and upgrading service equipment. Background technique [0002] Internet Protocol Television (IPTV for short) service is a brand-new business model, which brings consumers the Internet enjoyment integrating information, entertainment, learning and shopping. The existing TV can use the IPTV service through an IPTV Set Top Box (STB for short). [0003] In the actual use of the set-top box, due to the continuous introduction of related new services, the set-top box needs to install business plug-ins for new services from time to time, and the software platform of the set-top box itself also needs to constantly patch loopholes, which requires software upgrades for the set-top box. [0004] In an existing set-top box software upgrading method, the set-top box independently downloads a p...
