Abstract
The present invention relates to a contact-type inter-link button for a wireless general serial bus and a relative method. Each wireless USB device is provided with one inter-link button. An identity identification chip in each inter-link button comprises a unique identity of each wireless USB device. Before two devices are communicated for the first time, inter-link buttons of the two devices come in contact and are slightly pressed for completing the inter-link process of the two devices. Each inter-link button is mainly composed of a base and an inner core. When the two inter-link buttons are in mutual contact and are slightly pressed, the inner core is pressed into the base; a power supply in the base supplies electricity for the identity identification chip in the inner core; a panel of the inner core is used for forming a signal passage for completing the inter-link process of the devices. The method and the devices have the advantages of simple structure, low cost, convenient and rapid use, good confidentiality, novel design and broad purpose.
Description
Technical field
The present invention is a kind of contact device association method and device thereof that is applied to the radio universal serial bus of high-speed radio short haul connection.The invention belongs to communication technical field.
Background technology
USB (Universal Serial Bus, USB) be a kind of data transmission standard and the technology of Intel company's exploitation, the message transmission rate of its 2.0 version can reach 480 mbit/, has worldwide obtained at present using widely.Wireless USB is the data transmission technology standard of developing at present of new generation, and it utilizes ultra broadband, and (Ultra-Wideband, UWB) wireless communication technology replaces traditional cable, realizes being up to the wireless data transmission of 480 mbit/.Among the technical standard of Wireless USB is being formulated.
Device association is one of realization difficult point of Wireless USB.In wire communication, communication equipment links to each other by cable, and the identity validation of communicating pair does not have problems.Whether in radio communication, a side of communication has difficulties to the opposing party's identity validation, promptly can not determine and oneself communicate by letter with whom, at the devices communicating of communicating by letter with it with hope.Use encryption technology, promptly communicating pair uses the cipher key pair communication content of one group of agreement to encrypt, and can address this problem.But how allowing communicating pair all know this group key, also is the problem that needs solve.In the Wireless USB technology, this problem is called device association.
The wireless USB apparatus correlating method that proposes mainly contains three kinds at present.First kind is called cable mode, promptly before two equipment are communicated by letter for the first time, with a USB cable they is coupled together in wired mode, and interchange key is pulled out cable after finishing, and promptly can communicate with wireless mode later on, no longer needs cable.The major defect of this method is to make user's desired value to reduce greatly.Two equipment of the original expectation of user can radio communication, but also will connect with cable before the communication now, can feel not have the convenience of imagining.In addition, because the maximum length of USB cable is 2 meters, if the equipment apart from each other of communicating pair, volume is bigger again, connects with USB cable and also has any problem.Second kind of device association method is called figure pattern, promptly before two equipment carry out wireless data transmission for the first time, produce a random digit by a side, and be wirelessly sent to the opposing party, both sides are presented at this numeral on the screen, at this moment, observe this two numerals by the user, after confirming that these two numerals equate, finish device association.This method needs user's intervention more, needs to use complicated cryptographic protocol, also needs communication equipment that the display part is all arranged simultaneously, and this also can increase the cost of equipment.The third method is called the near-field communication pattern, promptly before two equipment are communicated by letter for the first time, adopts mode interchange key between them of near-field communication.Near-field communication utilizes the near-field effect of electromagnetic signal to communicate, and the distance of communication is generally in 10 centimetres.The near-field communication technology that is that non-contact transit IC card commonly used uses.Near field communication method requires two communication equipments to lean on very closely when device association, still have the possibility of divulging a secret during interchange key simultaneously, and the cost of the card reader of near-field communication is also than higher.
Summary of the invention
Technical problem: the objective of the invention is to solve problems such as device association method inconvenience in the communication of present Wireless USB, confidentiality be bad, a kind of convenience, good confidentiality are provided, simply are used for the contact associated buttons and the correlating method thereof of radio universal serial bus.
Technical scheme: the present invention proposes contact device association method, by the contact of button, finishes the device association in the Wireless USB communication.This associated buttons is made up of the inner core that pedestal and embedding pedestal also can slide in pedestal, pedestal upper and lower respectively have a metallic conductor respectively with pedestal in the positive and negative electrode of battery join, be called positive source and power cathode, be provided with a spring in the pedestal, the dividing plate in the pedestal separates battery and spring; In inner core, with positive source in the pedestal and the corresponding position of power cathode, two metallic conductors are arranged, when inner core is pressed when entering pedestal, these two metallic conductors will contact with positive source and power cathode respectively; An identification chip is arranged in the inner core, and its power pin links to each other with two metallic conductors respectively with ground pin.The input/output port of identification chip links to each other with the metal decking of inner core.
Its correlating method is that an associated buttons is arranged on each wireless USB apparatus, the unique identification that has comprised this equipment in the identification chip in the associated buttons, before two equipment are communicated by letter for the first time, with the associated buttons contact of two equipment, the light pressure, inner core is pressed into pedestal, can finish the association process of these two equipment; If two equipment volume are bigger, the form that can adopt associated buttons and equipment to separate when two equipment are separated by far, can be only taken off associated buttons and carry out association like this.
When two associated buttons be in contact with one another, when gently pressing, inner core is pressed and enters pedestal, the power pin of identification chip and ground pin will communicate with positive source and power cathode respectively, the identification chip is started working, at this moment, the input/output port of identification chip also is interconnected by metal decking, communicates, and finishes association process.After pressure disappeared, inner core was ejected by spring, and power supply is cut off, and associated buttons is returned to general state.
Associated buttons can be integrated on the wireless USB apparatus, also can separate with wireless USB apparatus.No matter integratedly still separate, all comprised the unique identification of this equipment in the identification chip in the associated buttons of each wireless USB apparatus.After two associated buttons contacts, the light pressure, the device association process that the wireless USB apparatus of these two associated buttons representatives is just finished.
Beneficial effect: the device association method and apparatus of the Wireless USB system that the present invention proposes, compare with existing method, have the following advantages:
1. simple in structure, cost is low;
2. easy to use, quick;
3. adopt the mode of contact to communicate by letter good confidentiality;
4. novel in design, can not reduce the desired value of user to wireless product;
5. be widely used, except the association of wireless USB apparatus, also can directly apply to the multiple identity that needs
The occasion of authentication.
