Abstract

The invention relates to a method for synchronizing public keys of an encryption device based on the NFC technology. The method comprises the steps that (1) an NFC label is arranged on a protruding shell unit on a USB concentrator body, an NFC processing chip is arranged on the hardware encryption device matched with a USB interface on the USB concentrator body in an inserted mode at the same, and the NFC processing chip is adjacent to the NFC label at a close range so that the NFC processing chip and the NFC label can sense each other when the hardware encryption device is inserted in the USB interface; (2) the hardware encryption device calls the NFC processing chip to read the content on the NFC label, if the content cannot be read, an error prompt is given and output, and if the content can be read, a safe state is started, and synchronization of the public keys is conducted. The method has the advantages that files encrypted on any client side of a user can be decrypted on the other client sides of the user, the encrypted files can be shared by all the client sides at the same time, and hostile attacks of hackers can be effectively prevented.

Description

A kind of synchronous method of encryption device PKI based on NFC technology
Technical field
The present invention relates to encryption device technical field, especially a kind of synchronous method of encryption device PKI based on NFC technology.
Background technology
Adding in Miyun dish implementation procedure, user's scene and need the problem solving to be: 1, a user has many clients (PC or mobile device), is inserted with a hardware encipher equipment (USB or TF card interface form) in every client; 2, the file of encrypting in any client of a user can both be decrypted on need to other clients this user; If 3 relations that can break the wall of mistrust between each hardware encipher equipment, just can realize sharing of encrypt file between each client.4, between encryption device, break the wall of mistrust in the process of relation and need to prevent hacker's malicious attack, and the relation that breaks the wall of mistrust between non-my encryption device.
Summary of the invention
The present invention will solve the shortcoming of above-mentioned prior art, and a kind of synchronous method of encryption device PKI based on NFC technology is provided.
The present invention solves the technical scheme that its technical matters adopts: this synchronous method of encryption device PKI based on NFC technology, the method comprises the steps:
(1), in usb hub main body, on outstanding housing unit, be provided with NFC label, be on the hardware encipher equipment coordinating of pegging graft and be provided with NFC process chip with the USB interface in usb hub main body simultaneously; NFC process chip and NFC label are closely adjacent, while making hardware encipher equipment be inserted in USB interface, can interact;
(2), hardware encipher equipment calls NFC process chip reads the content of NFC label, if can not, the wrong and pass-out of prompting; If can, enter safe condition, carry out PKI synchronous.
As preferably, user inputs PIN code and asks hardware encipher equipment 5 to enter safe condition, after PIN code checking is correct, then enters above-mentioned steps (2).
The effect that the present invention is useful is: realizing the file encrypted in any client a user can both be decrypted on need to other clients this user, the sharing of encrypt file between each client simultaneously, and can effectively prevent hacker's malicious attack.
Accompanying drawing explanation
Fig. 1 is hardware configuration schematic diagram of the present invention;
Fig. 2 is schematic flow sheet of the present invention.
Reference numeral: usb hub main body 1, housing unit 2, NFC label 3, NFC process chip 4, hardware encipher equipment 5, USB interface 6.
Embodiment
Below in conjunction with embodiment, the invention will be further described:
As shown in Figure 1,1 is usb hub agent structure, can connect PC by USB connecting line; 2 is the upper outstanding housing unit of usb hub main body (USB HUB), has placed a NFC label 3 on housing unit; 6 is USB interface; 5 is the hardware encipher equipment of USB interface, and its inside, except comprising hardware encipher deciphering module, also comprises a NFC process chip (can NFC process chip be conducted interviews and be controlled by COS), can read NFC label; The cloud shield of TF interface can be inserted on usb hub by TF-USB breakout box.In the time that the hardware encipher equipment of USB interface is inserted in usb hub main body, NFC process chip 4 just in time with housing unit on NFC label closely adjacent, can interact, after can allowing each USB interface encryption device be inserted on USB HUB, the NFC chip in USB interface encryption device can read the content of NFC label.
As shown in Figure 2, this synchronous method of encryption device PKI based on NFC technology, the method comprises the steps:
(1), in usb hub main body 1, on outstanding housing unit 2, be provided with NFC label 3, be on the hardware encipher equipment 5 coordinating of pegging graft and be provided with NFC process chip 4 with the USB interface 6 in usb hub main body 1 simultaneously; NFC process chip 4 is closely adjacent with NFC label 3, while making hardware encipher equipment 5 be inserted in USB interface 6, can interact;
(2), user inputs PIN code and asks hardware encipher equipment 5 to enter safe condition, after PIN code checking is correct, then enters step below;
(3), hardware encipher equipment 5 calls NFC process chip 4 and reads the content of NFC label 3, if can not, the wrong and pass-out of prompting; If can, enter safe condition, carry out PKI synchronous (only have in the time that the hardware encipher equipment 5 of USB interface reads NFC label 3, just allow to carry out the synchronous interface interchange of PKI).
In addition to the implementation, the present invention can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of requirement of the present invention.
