For enabling the above objects, features and advantages of the present invention to become apparent, preferred embodiment cited below particularly, and coordinate Appended accompanying drawing, is described in detail below.
Brief description
In order to be illustrated more clearly that the technical scheme of the embodiment of the present invention, below will be attached to use required in embodiment Figure is briefly described it will be appreciated that the following drawings illustrate only certain embodiments of the present invention, and it is right to be therefore not construed as The restriction of scope, for those of ordinary skill in the art, on the premise of not paying creative work, can also be according to this A little accompanying drawings obtain other related accompanying drawings.
Fig. 1 shows that a kind of flow process of middleware of set top box system authorization method that the embodiment of the present invention is provided is illustrated Figure；
Fig. 2 shows a kind of structural representation of middleware of set top box system authorization device that the embodiment of the present invention is provided Figure.
Specific embodiment
Purpose, technical scheme and advantage for making the embodiment of the present invention are clearer, below in conjunction with the embodiment of the present invention Middle accompanying drawing, the technical scheme in the embodiment of the present invention is clearly and completely described it is clear that described embodiment only It is a part of embodiment of the present invention, rather than whole embodiments.The present invention generally described and illustrated in accompanying drawing herein is real The assembly applying example can be arranged with various different configurations and design.Therefore, below to the present invention's providing in the accompanying drawings The detailed description of embodiment is not intended to limit the scope of claimed invention, but is merely representative of the selected reality of the present invention Apply example.Based on embodiments of the invention, the institute that those skilled in the art are obtained on the premise of not making creative work There is other embodiment, broadly fall into the scope of protection of the invention.
Embodiment as shown in Figure 1, provides a kind of middleware of set top box system authorization method in the embodiment of the present invention, bag Include following steps：
Step 100, unique mark SN of acquisition Set Top Box itself；
Step 120, above-mentioned unique mark SN is sent to authorization card, request authorizes；Wherein, this authorization card is inserted into State in Set Top Box；
If step 140 authorization card has authorization privilege, receive the authorization code AC that authorization card sends；This authorization code AC It is to be generated according to above-mentioned unique mark SN by above-mentioned authorization card；
Step 160, authorization code AC is written to Set Top Box authorization message region；
Step 180, transmission authorize successful feedback information to authorization card.
In the present embodiment, Set Top Box manufacturer needs to take the authorization card of software vendor, and authorization card is inserted into machine top In box, then Set Top Box is automatically and this authorization card carries out coordinating the mandate completing middleware system, and then completes Set Top Box and dispatch from the factory When mandate；Above-mentioned authorization card is inserted into inside Set Top Box, and when this authorization card possesses authorization privilege, Set Top Box obtains automatically Unique mark SN of itself, this unique mark SN is the product ID of Set Top Box, is the ID card No. of product；Set Top Box After unique mark SN automatically obtaining its own, this unique mark SN is sent to authorization card, request authorizes, if authorized Card with no authorized authority, then can return inaccurate mandate to Set Top Box, terminate this authorization requests；If authorization card has mandate power Limit, then authorization card receive and authorization code AC can be generated according to this unique mark SN after this unique mark SN, and by this authorization code AC Send to Set Top Box, this authorization code is written to Set Top Box authorization message region by Set Top Box, and Set Top Box sends and authorizes successfully Feedback information to authorization card, this authorization card receive Set Top Box return mandate successful information feedback after, licensing process tie Bundle.
In above-described embodiment, in whole licensing process, do not rely on bilateral network, there is mandate success rate high, safe and reliable Good effect.
Further, for the Set Top Box having issued, Set Top Box enters into using after in user's hand after dispatching from the factory, When Set Top Box detects itself and first powers on, Set Top Box mandate verification can be carried out, it authorizes the process of verification to include：
Fixing public key and upconverter ACU module is prestored in middleware system；
In middleware system initialization procedure, read the mandate in unique mark SN and authorization message region of Set Top Box Code AC；
By above-mentioned upconverter ACU module, authorization code AC is decrypted, is reduced into authorization message；Why enter The process of row deciphering, is because that authorization code AC is unique mark SN or the other information encryption generation by Set Top Box, The process of deciphering reduction is exactly the process of a deciphering, meeting corresponding unique mark SN of authorized code AC after deciphering, if should The SN that unique mark SN reads with Set Top Box is corresponding, and mandate can be successful；Therefore above-mentioned process is deciphered, by authorization code AC After being reduced into authorization message (comprising SN in this authorization message), also that this authorization message and described Set Top Box itself is unique Mark SN compares, if described authorization message is consistent with unique mark SN of described Set Top Box itself, authorizes verification Pass through；When authorizing after verification passes through, then explanation Set Top Box passes through to authorize, then Set Top Box can according to its receive corresponding Operational order enters into digital television function.
If above-mentioned authorization message is inconsistent with unique mark SN of Set Top Box, verification is authorized not pass through；Work as mandate Verification is not passed through, then point out unauthorized, now can start aerial authorization flow and carry out the mandate to Set Top Box；
Further, above-mentioned aerial authorization flow, including：
Set Top Box filters to privately owned table package identification PID according to authorization data；
The authorization data being filtered in privately owned table being analyzed, awarding when there is the super of Set Top Box producer in this privately owned table Flexible strategy according to when, then be considered as the super mandate to the machine, authorize forever effectively in the case of preserve authorization code AC；When described privately owned Exist in table Set Top Box native data when, then be considered as the direct mandate to the machine, and preserve corresponding authorization code AC；Wherein, Super mandate refers to not differentiate between the mandate of Set Top Box, as long as taking super mandate, any Set Top Box can use, native data (or direct mandate) refers to the mandate of simply this Set Top Box, and other Set Top Boxes can not use.
Wherein, above-mentioned Set Top Box filters to described privately owned table package identification PID according to authorization data, including：
Open wave filter Filter and filter privately owned table package identification PID.
For ease of understanding, it should be noted that above-mentioned PID is package identification, it is DTV proprietary term, and DVB standard organization prescribed standard PID and tableID, the ID outside corresponding regulation, it is commonly referred to as privately owned ID.
Above-mentioned, carry out authorizing verification after Set Top Box dispatches from the factory, verify the aerial authorization flow of obstructed out-of-date unlatching when authorizing Authorized it is ensured that Set Top Box can normally be used by mandate, equally be there is the good effect authorizing success rate high.
Embodiment as shown in Figure 2, provides a kind of middleware of set top box system authorization device, this device in the present embodiment Including：
Acquisition module 200, for obtaining unique mark SN of Set Top Box itself；
First sending module 220, for sending described unique mark SN to authorization card, request authorizes；Wherein, described award Power card is inserted in described Set Top Box；
