Abstract
The utility model discloses a double-chip intelligent card supporting a national crypto algorithm in the technical field of intelligent cards. The intelligent card comprises a national crypto security chip, an SWP chip, and SIM card pins, wherein the national crypto security chip is connected with the SWP chip and the C7 pin of an SIM card, and the SWP chip is connected with the national crypto chip and the C6 pin of the SIM card. The intelligent card can be used for the businesses of mobile payment and national crypto authentication at the same time, and solves a problem that a present mainstream national-crypto chip and the technical scheme of NFC mobile payment cannot be achieved at the same time.
Description
Technical field
The utility model relates to the smart card in a kind of wireless communication technique field, specifically a kind of dual chip is supported the smart card of the close algorithm of state.
Background technology
The close algorithm of state is that national Password Management office is for ensureing national information safety, the algorithm of the independent research of release.Internal information, administrative affair information, economic information that is mainly used in not relating to state secret content but has susceptibility etc. is encrypted protection.Such as: the close algorithm of state can be used for transmission encryption, the storage encryption of all kinds of sensitive informations of enterprise's entrance guard management, enterprises, prevents illegal third party's obtaining information content; Also can be used for various safety certifications, Web bank, digital signature etc.
Development along with wireless communication technique and NFC technology, the close algorithmic technique of state also applies in SIM card more and more, comprise the SWP-SIM(SingleWireProtocol based on 13.56MHz, single-wire-protocol SIM) block grade with the mobile payment SIM card product of radio-frequency enabled.
Yet the close algorithm of state must the national Password Management of employing office authenticate the safety chip passing through, this class chip kind is less, and requires as domestic.Support that at present the majority of SWP-SIM card radio-frequency enabled is external chip manufacturers design, cannot authenticate by the right close algorithm of state of national Password Management office, bring resistance therefore to the close application of state based on mobile device.
Utility model content
The utility model is for prior art above shortcomings, propose a kind of dual chip and support the smart card of the close algorithm of state, can be applied to the close authentication business of mobile payment and state simultaneously, solve the problem that the close chip of current main flow state and NFC mobile payment technical scheme cannot have both simultaneously.
The utility model is achieved through the following technical solutions, this smart card comprises: the close safety chip of state, SWP chip and SIM card pin, wherein: the close safety chip of state is connected with the C7 pin of SWP chip and SIM card respectively, SWP chip is connected with the C6 pin of the close safety chip of state and SIM card respectively.
Described SWP chip is supported 13.56M SWP agreement;
The close safety chip of described state is supported the close algorithm of state.
The close safety chip of described state comprises: the first IO interface, central processing unit, application switch and the second IO interface that connect successively, and the close application controller of state being connected with application switch with central processing unit respectively.
The first described IO interface and the second IO interface are mobile terminal contact.
Utilize the utility model can on a card, dispose the close algorithm arrangement of SWP scheme and state simultaneously, be applicable to different scenes.

Embodiment
Below embodiment of the present utility model is elaborated; the present embodiment is implemented take technical solutions of the utility model under prerequisite; provided detailed embodiment and concrete operating process, but protection domain of the present utility model is not limited to following embodiment.
As shown in Figure 1, the present embodiment SWP-SIM card 0 comprises: the close safety chip 1 of state, SWP chip 2 and SIM card pin C6, C7, wherein: the close safety chip 1 of state is connected with the C7 pin of SWP chip and SIM card respectively, SWP chip 2 is connected with the C6 pin of the close safety chip of state and SIM card respectively.
The APDU instruction and the response message that meet 7816 agreements that the close safety chip 1 of described state sends from mobile terminal by the transmission of C7 pin; Described SWP chip 2 meets the command information of SWP agreement with the CLF chip in mobile terminal by the transmission of SIM card C6 pin; Meet the command information of 7816 agreements with state close safety chip 1 transmission.
Described closely noncontact SWP chip 2 is supported the SWP(single-wire-protocol of 13.56MHz), the close safety chip 1 of described state is supported the close algorithm of state.
As shown in Figure 2, the close safety chip 1 of described state comprises: the first IO interface IO1, central processor CPU, application switch SWP and the second IO interface IO2 that connect successively, and the close application controller GM of state being connected with application switch SWP with central processor CPU respectively.
Described the first IO interface IO1 and the second IO interface IO2 are mobile terminal contact.
The 7816 contact instructions that the first described IO interface IO1 interface sends by C7 pin mobile terminal receive also export central processor CPU to.
Described central processor CPU is distinguished the application type comprising in contact instruction, processing instruction for SWP chip application is exported to application switch SWP, by passing through for the instruction of close safety chip 1 application of state, after the close application controller processing of state, to mobile terminal IO1 interface, exported execution result feedback by the second IO interface IO2 interface.
