Embodiment
A kind of terminal credit method flow diagram that Fig. 1 provides for the embodiment of the invention.As shown in Figure 1, the terminal credit method that present embodiment provides specifically can be applied to the credit process at terminal, and the terminal specifically can be mobile phone, panel computer, personal computer etc.The terminal credit method that present embodiment provides specifically comprises:
Step U10, the credit services request of sending the characteristic information carry the terminal to the credit server;
But the terminal specifically can be to service provider's acquisition request telecommunications services, but the service provider will confirm that this terminal was a trusted terminal before telecommunications services is being provided for the terminal.The credit server can be the server that credit is carried out at the terminal that is used to of service provider's setting.The credit services request is sent to the credit server in the terminal, so that the credit server carries out the credit service to the terminal.
The corresponding initial credit service of credit services request that step U20, reception credit server send is divided storage area according to initial credit service;
The credit services request that the credit server sends according to the terminal is for the terminal provides initial credit service.Initial credit service is specially that the credit server generates according to the characteristic information at the terminal in the credit services request.The characteristic information at terminal specifically can be the characteristic information to terminal hardware module and version extraction.The terminal receives initial credit service, and divides storage area according to this initial credit service, and thinking to trust to inject provides storage area.Initial credit service is specially the indication information that carries out the memory block division operation in order to indicating terminal.The division of storage area can be carried out according to the relevant indication that the memory block of carrying in the initial credit service is divided in the terminal.As on the storage card at terminal, carrying out the original position that storage area is divided, area size, form etc.
Step U30, receive the service integrated information that the credit server sends, and will serve integrated information and be loaded into storage area, with storage area as trusted source;
The service integrated information is specially authorization server and generates according to the characteristic information at terminal, and the service integrated information can comprise that specifically operating system is provided with that information, interface between software and hardware are provided with information, information is set final drive and credible service software is provided with information etc.The terminal receives the service integrated information that authorization server sends, and will serve integrated information and be loaded into storage area, and storage area as trusted source, is promptly realized trusting injection.To serve integrated information is loaded into and is specially in the storage area the integrated information reproduction of service to storage area and carry out start-up course.
Step U40, according to the service integrated information chain that breaks the wall of mistrust, and trust chain verified, if verify successfully, but then obtain request to credit server transmission telecommunications services;
Particularly, restart this trusted source that the credit server provides at the terminal as new trusted source, and the chain that breaks the wall of mistrust carries out the checking of trust chain in start-up course, realizes trusting and transmit.To the checking of trust chain specifically comprise before starting integrity verification with start in authentication, if verify successfully, but but the telecommunications services that then is used to obtain telecommunications services to the transmission of credit server is obtained request.
But but the corresponding telecommunications services of the telecommunications services request of obtaining of step U50, the transmission of reception credit server.
At this moment, but this terminal just can be used as trusted terminal has received telecommunications services that the credit server provides.But specifically also can be provided with in addition in order to the server that telecommunications services is provided be but that the terminal provides telecommunications services to the service provider.Credit service in reality provides in the process; Specifically can protect this process through security mechanism; The credit service can be carried out through the physical loading mode of off-line, also can carry out through the online load mode of safety chain, can improve the fail safe of credit service.
The terminal credit method that present embodiment provides; Divide storage area according to initial credit service; To serve integrated information and be loaded into storage area, with the storage area that is mounted with the service integrated information as trusted source, according to the service integrated information chain that breaks the wall of mistrust; And trust chain verified, to realize the credible of terminal.Because the service integrated information is provided by the credit server, guarantees the credibility of trusted source, carries out the foundation of trust chain more successively, and trust chain is verified, realize trusting and transmit.The hardware configuration that need not to change the terminal just can be realized the credible of terminal, has improved the flexibility of terminal credit.
In the present embodiment, step U20 receives the corresponding initial credit service of credit services request that the credit server sends, and divides storage area according to initial credit service, specifically can comprise:
Receive the authorization information that the credit server sends, and authorization information is verified,, then receive the initial credit service that the credit server sends, divide storage area through the physical isolation mode according to initial credit service if verify successfully.
Particularly, the credit services request that the credit server can at first send according to the terminal is verified the identity at terminal, with the legitimacy of verification terminal identity.If verify successfully and then send authorization information and initial credit service to the terminal, so that the bidirectional safe authentication of realization authentication is verified at the terminal to the identity of credit server.Divide storage area according to initial credit service through the physical isolation mode, the storage area that is used to trust injection is physically-isolated, on hardware, has guaranteed the fail safe of storage area, and the credibility with this trusted source that forms further is provided.
In the present embodiment, step U50, but but receive after the corresponding telecommunications services of the telecommunications services request of obtaining that the credit server sends, specifically can also comprise the steps:
Step U60, but telecommunications services is verified, if verify successfully, but startup telecommunications services then.
The another kind of terminal credit method flow diagram that Fig. 2 provides for the embodiment of the invention.As shown in Figure 2, the terminal credit method that present embodiment provides specifically can be applied to the credit process of server side to the terminal, specifically can cooperate realization with the terminal credit method that is applied to end side that any embodiment of the present invention provides, and this repeats no more.The terminal credit method that present embodiment provides can be carried out by the credit server that the service provider is provided with.
The credit method that present embodiment provides specifically comprises:
