Bi-directional set-top box authentication method, system and related equipment

Abstract

The embodiment of the invention discloses a two-way set-top box authentication method and a two-way set-top box, wherein the two-way set-top box comprises a conditional access module, and the method comprises the following steps: acquiring authentication information which is encrypted through a personal allocation key; decrypting the encrypted authentication information by using the conditional access module to acquire the decrypted authentication information, wherein the personal allocation key is stored in the conditional access module; and performing authentication on a network side by using the decrypted authentication information. By adopting the proposal of the embodiment, the usability and the compatibility are also ensured while the security of the IP network access of the two-way set-top box is ensured.

Description

technical field [0001] The invention relates to the communication field, in particular to a two-way set-top box authentication method, system and related equipment. Background technique [0002] The two-way set-top box and the network have two connection links of Cable and Internet Protocol (Internet Protocol, IP), so that the two-way set-top box can not only receive the video content sent by Cable broadcast, but also interact with the service provider through the IP link. [0003] During the process of implementing the present invention, the inventors found that the security of the content transmitted through the Cable link is guaranteed through the Conditional Access (CA) system. And when using IP network, usually use the two-way set-top box number of two-way set-top box or the two-way set-top box identification (ID) of the CA module in the two-way set-top box to carry out authentication to the server of IP network side, to guarantee the access authentication of IP network...

AI Technical Summary

Problems solved by technology

In this solution, since the ID of the two-way set-top box can be easily obtained, copied, or even stolen by the construction personnel or the user of the two-way set-top box, there is a relatively large security risk

[0004] In other solutions to ensure the security of IP network access authentication, either the user is required to manually enter the encryption password, or the CA module in the two-way set-top box needs to be changed, and there are corresponding operability, compatibility, security issues

[0005] It can be seen that in the prior art, when the two-way set-top box performs operations such as access authentication of the IP network, there are problems in its information security, and it is impossible to take into account the ease of use while ensuring the security of the IP network access of the two-way set-top box and compatibility
