Abstract
The utility model discloses a multifunctional secure digital (SD) card. The multifunctional SD card comprises a power supply port, a security certification module and a switch, wherein the power supply port is used for supplying power; the security certification module is used for certification; the switch is positioned outside the multifunctional SD card; and one end of the switch is connected with the power supply port, and the other end of the switch is connected with the security certification module. By adoption of the embodiment of the utility model, the security certification module can be safely used.
Description
Technical field
The utility model relates to technical field of storage card, more specifically, relates to a kind of multi-functional SD card.
Background technology
Based on the wireless telecommunications of storage card (MICROSD card, SD card etc.), wireless payment and online on-line payment technology in the fields of society widespread use.Along with the expansion of more application and development and customer group, the security of storage card receives much attention, and the SD-KEY card is exactly the technology that proposes to above-mentioned situation, at home and abroad is widely used at present.
The SD-KEY card is a kind of multi-functional SD card; Possess KEY, data storage and data encrypting and deciphering three big functions simultaneously; Blocking built-in security authentication module provides various Secure Application through the SD interface, comprises authentication, digital signature, access rights control and data encrypting and deciphering etc.The SD-KEY card adopts multiple packing forms such as Standard SD, Mini SD, Micro SD, and the same with common SD card possess superpower equipment access capability.Can be applied to: each link of safety E-mail, web access, VPN and local simple login authentication and ecommerce, E-Government, Web bank.
The SD-KEY card only requires in process of exchange security authentication module to power on based on security consideration to carry out authentication, and security authentication module is in off-position in the time of need not using, and so just needs to control separately the power supply state of security authentication module in the SD-KEY card.
The control mode of security authentication module power supply mainly contains following several kinds in the SD-KEY card at present:
1, referring to accompanying drawing 1, have low pressure difference linear voltage regulator (LDO) module in the SD controller in the SD-KEY card, through sending the SD control order security authentication module is supplied power to the LDO module.
2, referring to accompanying drawing 2, SD controller input and output (IO) are connected to security authentication module through cmos switch in the SD-KEY card, and the SD controller sends order IO through cmos switch security authentication module is supplied power.
No matter be control LDO power supply, still control the IO power supply, all need the order of SD controller to operate.The SD controller is very easily intruded into the trojan horse program control in the computer that links to each other with the SD controller, and the security function of security authentication module has just lost effect like this.
The utility model content
The utility model embodiment proposes a kind of multi-functional SD card, the safe handling of the authentication module that can ensure safety.
The technical scheme of the utility model embodiment is following:
A kind of multi-functional SD card, said multi-functional SD card comprises: power supply port, security authentication module and switch,
The power supply port is used to provide electric power;
Security authentication module is used to carry out authentication;
Switch is positioned at the outside of multi-functional SD card, and an end of switch connects the power supply port, and the other end of switch is connected with security authentication module.
When said switch is in off-state, the disconnection that is connected of power supply port and security authentication module, security authentication module quits work.
Said switch is in closure state, and the power supply port is connected with security authentication module, and the power supply port is supplied power the security authentication module operate as normal to security authentication module.
Can find out that from technique scheme in the utility model embodiment, multi-functional SD card comprises power supply port, security authentication module and switch, the power supply port is used to provide electric power; Security authentication module is used to carry out authentication; Switch is positioned at the outside of multi-functional SD card, and an end of switch connects the power supply port, and the other end of switch is connected with security authentication module.Avoid like this through the work of signaling control security authentication module, even there is also uncontrollable security authentication module in trojan horse program, the safe handling of the authentication module that therefore can ensure safety.
Description of drawings
Fig. 1 is the structural representation of prior art 1;
Fig. 2 is the structural representation of prior art 2;
Fig. 3 is the structural representation of multi-functional SD card.
Embodiment
For the purpose, technical scheme and the advantage that make the utility model are expressed clearlyer, the utility model is remake further detailed explanation below in conjunction with accompanying drawing and specific embodiment.
In the utility model embodiment; By manual work powering on through switch control security authentication module; Replaced the SD controller to power on, avoided the trojan horse program invasion and the safety problem of existence, the safe handling of the authentication module that can ensure safety through the instruction control security authentication module.
In the utility model, multi-functional SD card also comprises a switch except that comprising existing structure.This switch places the outside of multi-functional SD card.Use multi-functional SD card, when needs carried out authentication, then with switch closure, the power supply port was connected with security authentication module, and the power supply port is supplied power to security authentication module, operate as normal after security authentication module powers on.In the time of need not carrying out authentication, switch is in off-state, the disconnection that is connected of power supply port and security authentication module, and security authentication module quits work.Physically the power supply of security authentication module is being controlled like this.Can avoid the power supply port of security authentication module being controlled the trojan horse program control security authentication module that causes through the SD control order.The security that the technical scheme of employing the utility model has not only improved security authentication module in the multi-functional SD card, and manufacture craft is simple, is convenient to large-scale production.
The above is merely the preferred embodiment of the utility model, is not the protection domain that is used to limit the utility model.All within the spirit and principle of the utility model, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection domain of the utility model.
Claims (3)
1. a multi-functional SD card is characterized in that, said multi-functional SD card comprises: power supply port, security authentication module and switch,
The power supply port is used to provide electric power;
