Embodiment
For the purpose, technical scheme and the advantage that make the embodiment of the invention is clearer, specific embodiment is described in detail below in conjunction with accompanying drawing.
The present invention provides a kind of business cipher key synchronous method in mobile multimedia broadcast system, is used for functions such as obtaining of mobile multimedia broadcast system support terminal when roaming business cipher key.
Fig. 1 is the flow chart of steps of method for synchronous of the present invention, and as shown in the figure, the method for mobile multi-media broadcasting service key synchronization comprises:
Wherein, described central M-CAS is central M-CAS, and described central business cipher key is the free pairing business cipher key of secure service channel in the whole nation; Described regional M-CAS is for economizing M-CAS, and described area business key is the business cipher key of this province's business and this province institute jurisdiction city business; Pass through business cipher key encipher interface transport service secret key encryption request between each described regional M-CAS and encrypt the back business cipher key.
Fig. 2 is the synchronous schematic diagram of business cipher key of the present invention, and as shown in Figure 2, business cipher key specifically comprises following steps synchronously:
1), central M-CAS generates central professional corresponding service key, and is and synchronous to each province M-CAS by IF1 interface (central platform interface).Especially, for the free secure service channel in all whole nations, use same business cipher key, generated by central M-CAS, the IF1 interface is given the each province synchronously, and SKID consults configuration, and specifically value is referring to appendix: the SKID coding rule.
2), each province M-CAS generates the business cipher key of this province's business, institute's jurisdiction city business, and by IF2 interface (regional platform interface), to central M-CAS all business cipher keys of this province synchronously.
3), central M-CAS is also by the IF1 interface, to the business cipher key that other provinces (or all are economized) synchronized transmission each province is transmitted synchronously, realize all business cipher keys of the whole network each province M-CAS, central M-CAS synchronously.
4), in addition, each province M-CAS can be to central M-CAS request synchronous service key, and this interface is optional.
5), when the user roams, user visiting ground province M-CAS economizes the business cipher key that M-CAS request user key is encrypted from user ascription area by IF3 interface (business cipher key encipher interface).
As shown in Figure 3, network configuration of the present invention comprises: M-CAS, mobile communications network NAF (network application function entity), portable terminal etc.
M-CAS: be responsible for the business cipher key management with synchronously, and the ciphered program stream secrete key, functions such as User Status and order relations management and authentication.
Mobile communications network NAF (network application function entity): major function is to finish the encapsulation of business cipher key message and user key management and professional control.
Portable terminal: comprise mobile communication equipments such as mobile phone.Be responsible for to receive, represent ESG information, and the service of two-way request Mobile Multimedia Broadcasting, comprise and obtain SK, and represent function such as business tine.
In the mobile multimedia broadcast system, BOSS (Business Operation Support System, business operation support system), ESG (electron service instruction) all have the deployment of districts and cities, province, central node.M-CAS is central authorities, the regional networking structure of economizing more.
For CAS, the function of economize, central node being disposed is not quite similar.Described referring to form 1, form 2 and form 3.
Form 1 abbreviation
The functional module of form 2 central authorities, province, districts and cities CAS
Form 3 each functional module are described
As shown in Figure 4, for roaming terminal of the present invention obtains the business cipher key schematic diagram, comprise following technical step:
1). broadcasting and TV each province platform M-CAS and the synchronous SK of central M-CAS the whole network.
2). customer mobile terminal is economized M-CAS (the R broadcasting and TV are economized M-CAS) to the roaming place broadcasting and TV and is obtained the SK request by mobile communications network NAF, and request message carries mobile user identification and CMMB user ID (CMMBSN), SKID etc.
3). the SKID that roaming place broadcasting and TV province M-CAS carries according to subscription request message searches corresponding PurchaseItemID, carry the one or more PurchaseItemID that find and economize M-CAS (the H broadcasting and TV are economized M-CAS) request use this user (CMMBSN) user key, encrypt SKID corresponding service key to the user ascription area broadcasting and TV.
4). the ownership place broadcasting and TV are economized M-CAS this user's order relations and User Status are carried out authentication, send SK, CMMBSN to encryption equipment, and close back SK is encrypted and obtains in request.
5). the roaming place broadcasting and TV are economized M-CAS with close back SK, send to the mobile network from response message and economize platform, and then send to terminal.
SK is synchronously and obtain the interface message that flow process uses and can adopt as giving a definition in the above-mentioned mobile multimedia broadcast system:
One, SK sync cap--IF1 and IF2
Radio network is inner to be used.Comprise:
The CAS--of central authorities＞each province M-CAS, synchronous central business cipher key and other each province's business cipher keys;
Each province M-CAS--＞central M-CAS, the business cipher key of this province synchronously.
Form 6-1SKSync.REQ message
Under situations such as manual renewal SK, may exist has two or more SK the same moon, and this moment, the Mode value 0.
Form 6-2SKSync.RES message
Two, encrypt SK interface-IF3
Radio network is inner to be used.
Roaming economizes platform M-CAS-＞ownership and economizes interface use between the platform M-CAS system.
Form 6-3 encrypts the SK request message
Form 6-4 encrypts the SK response message
In a word, the invention provides the synchronous method of a kind of business cipher key, be used for functions such as obtaining of mobile multimedia broadcast system support terminal when roaming business cipher key.
Among the present invention, active synchronization BOSS information of managing not between the M-CAS.These information comprise: information, order relations such as user profile, package information, business.These information of central authorities, province CAS are all from the BOSS synchronization gain of corresponding central, province, and user profile, order relations are only managed at user ascription area M-CAS.And the data volume of SK own is wanted much less with respect to user profile, order relations etc.Thereby the present invention reduced M-CAS synchrodata amount, promoted M-CAS overall system performance, reliability.And exploitation of innovation ground method has realized synchronously and has obtained SK, supported mobile multi-media broadcasting service preferably.
The above only is a preferred implementation of the present invention; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the principle of the invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
