Description
Technical field
The invention belongs to cloud computing and virtual machine technique field, particularly relate to a kind of method of multiple users share soft ware authorization USB device.
Background technology
Along with the develop rapidly of computer techno-stress, the shortcoming of the secure context of traditional character authentication mode is more and more obvious.Traditional character type software license is cracked and piracy on a large scale, makes software service company suffer huge economic loss.
Along with the development of safety technique, service provider by secure authenticated information solidification in the usb device, makes authentication information not be extracted and to crack.Like this, when only having corresponding correct USB device, just by the certification of safety.Effectively can ensure the security of software, and be convenient to service provider and manage.
Because USB device itself has certain manufacturing cost, and major part is with being use corresponding service the short time per family, so for most of user, the authentication service of use USB type, can make the use cost of software greatly improve.Now be badly in need of wanting a kind of dispatching method of multiple users share USB authenticating device resource to manage USB authenticating device resource, so that the USB authenticating device both having met user uses needs, shared USB authenticating device resource can be maximized again, effectively reduce cost.
Summary of the invention
Because the above-mentioned defect of prior art, technical matters to be solved by this invention is to provide one can maximize shared USB authenticating device resource, and the method for the lower multiple users share soft ware authorization USB device of cost.
For achieving the above object, the invention provides a kind of method of multiple users share soft ware authorization USB device, comprise the following steps:
Step one, registration USB;
Step 2, registration service,
Step 3, request use USB device,
Step 4, the USB device that starts,
Step 5, end USB device;
Request described in step 3 uses USB device to carry out according to the following steps:
A1, when user have use the needing of USB device time, file a request to administration module; Judge whether user has VM; If user has VM, then inquire about the USB device reservation table of VM, according to USB device reservation table application USB device; When user does not have VM to use USB device, then create the VM of band USB device;
After A2, administration module receive request, request is processed; Judge that user is the request of renewing a contract, newly-built VM+USB asks or have VM+USB request; Check that whether the request of user is effective;
A3, record is carried out to the request of user; Judge that user is the need of renewed treaty;
If user needs to renew a contract, then directly renew a contract, then terminate; Otherwise execution step 4;
In step 4, described beginning USB device is carried out according to the following steps:
USB device in administration module quantitative check system is safeguarded:
B1, check whether the request that will start;
B2, when have will start request, then whether the resource in check system meets user; Otherwise terminate;
B3, when the resource in system meets user, to send request to USB explorer and Hypervisor; When the resource in system does not meet user, the USB device of user is delayed service time, and notifies user;
B4, administration module check the current state of USB device: if be idle condition, then the link information of USB device is sent to Hypervisor;
If be not idle condition, then inquire the VM of current this USB device of use, user and host Hypervisor information;
B5, send notice to previous user;
B6, administration module send request to former VM host Hypervisor, and the appointment USB device of VM is specified in unloading;
B7, the link information of USB device is sent to the host Hypervisor of new VM;
B8, administration module send request to Hypervisor, carry link information and the VM information of USB device; Hypervisor creates the VM of band USB device according to request and is that existing VM adds USB device;
Terminate USB device in step 5 to carry out according to the following steps:
USB device in administration module quantitative check system is safeguarded:
C1, check whether and will overduely ask; Overduely will ask if had, in check system, whether have enough resources to allow user to renew a contract:
If there are enough resources to allow user to continue to use in system, then first preempt resource, the information that then sends is pointed out to user; If user renews a contract before expiring, then camp-on resource is discharged, otherwise return execution step 3;
If allow user to continue to use without enough resources in system, then send information and will expire to point out its USB device to user;
C2, to send request to Hypervisor, carry link information and the VM information of USB device; Hypervisor deletes the VM of band USB device according to request.
Preferably, before described step 4, also comprise user and propose amendment to administration module or cancel the step of USB device request; After administration module receives the request of user, the request of user in record or renewed treaty request are modified or cancelled.
Preferably, step one is carried out according to the following steps:
D1, judge that service corresponding to USB device exists; If there is no, service is created in systems in which, and the relevant information of record service, comprise title, version number, issuing time, company information, software type and use description, then performing next step; If existed, then directly carry out next step;
D2, access USB device: first USB device is inserted unified USB interface bus; Scanning USB device; The USB device record newly inserted to be gone forward side by side row labels.
Preferably, step 2 is carried out according to the following steps:
E1, find new USB device;
E2, USB is associated with corresponding service;
E3, set up agent list for USB device, record the service condition of current USB device and corresponding use information.
Whether preferably, in described step 3, according to the authority of user and the validity of amount examination & verification user request, reexamining available resources in system and mate with the request of user, if coupling, is user's reservation or Resources allocation; If do not mated, then provide suggested design to user, mail notification client, and ensure in finite time effective; If user accepts suggested design, then determine that suggested design is true reservation; If user does not accept suggested design, then re-start selection; When system connects the request of accepted user, then USB device is mounted to user virtual machine, and according to the service condition of user user is notified and point out.
The invention has the beneficial effects as follows: the present invention when only configuring a USB virtual equipment card, more can meet the demand of user, and improve the utilization factor of USB device, effectively saved the cost that resource and user use software.
