Abstract
The invention relates to a method for confirming license acquisition, which includes the following steps: a client end sends negotiation request for license acquisition to a license server and negotiates with the license server about protocol edition and communications algorithm; the license server receives the negotiation request, and after negotiation informs the client end of the to-be-selected protocol edition and communications algorithm; the client end sends license acquisition request to the license server and attaches information related to the selected protocol edition and communications algorithm to the request; the license server receives the license acquisition request and then gives the client end a response containing the license; the client end sends conformation request for license acquisition to the license server; the license server informs the client end of processing state of the conformation request for license acquisition after receiving the confirmation request. With the method, such deficiencies as over-charging and wrong-charging caused by the fact that the license server cannot confirm correct license acquisition by the client end are overcome.
Description
Technical field
The present invention relates to digital copyright management (DRM) field, relate in particular to a kind of method of confirming that licence obtains.
Background technology
Licence in present digital copyright management obtains in the agreement, there is not the definition license server after licence is sent to client, client sends to the affirmation response message of license server, makes license server can't confirm whether client has correctly received licence.And whether client receives licence is very critical step and information in the DRM system, and license server is necessary to finish important steps such as charging according to this information.If license server can not be confirmed client and whether correctly receive licence, charge, situations such as wrong charging then appear probably.Therefore, just need a kind of method to solve the problems referred to above.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of method of confirming that licence obtains, can not confirm to overcome license server whether client correctly receives shortcomings such as the many chargings that caused under the situation of licence, wrong charging.
In order to solve the problems of the technologies described above, the invention provides a kind of method of confirming that licence obtains, this method comprises:
(1) client sends the negotiation request of obtaining licence to license server, carries out the negotiation of the protocol version and the communication of algorithms with license server;
(2) license server is received described negotiation request, the notice client will be selected after consulting the protocol version and the communication of algorithms;
(3) client sends to license server and obtains license request, and adds the relevant information that draws according to selected agreement and the communication of algorithms in this request;
(4) license server receive described additional have relevant information obtain license request after, give response that includes licence of client;
(5) client sends the affirmation request that licence obtains to license server;
(6) after license server was received described affirmation request, the notice client was obtained licence and is confirmed the processing of request result.
Wherein, described step (6) also comprises, if client is received the success response that license server is returned, just then client can be used described licence, otherwise, abandon this licence.
Wherein, the described communication of algorithms of step (3) comprises: the cryptographic algorithm of communication key and hashing algorithm.
Wherein, the affirmation request package obtained of the described licence of step (5) contains the reception installment state information of licence sign and this licence.
Wherein, licence is cancelled agreement and comprised two message in the described selected agreement: licence confirms that request and licence confirm response.
Whether wherein, described licence confirms that request message is sent to the license server end from client, be used for confirming successfully to receive and the installation license card to license server.
Wherein, described licence is confirmed to receive the response to be sent to client from the license server end, and the licence of customer in response end is confirmed request message.
A kind of method of confirming that licence obtains of the present invention has overcome license server and can not confirm whether client correctly receives shortcomings such as the many chargings that caused under the situation of licence, wrong charging.
Description of drawings
Fig. 1 is the schematic flow sheet that obtains according to the described affirmation licence of the embodiment of the invention.
Embodiment
Below in conjunction with accompanying drawing the present invention is described in further detail.
With reference to figure 1, the schematic flow sheet that obtains for the described affirmation licence of the embodiment of the invention.Detailed process is as follows:
Step 110: client is initiated to obtain licence to license server and is consulted request ClientLicHello, wishes to hold consultation with license server with regard to protocol version and the communication of algorithms etc.
Step 120: license server is responded the request of client, informs the protocol version that client is selected and the communication of algorithms etc. by ServerLicHello.
Step 130: client initiates to obtain license request LicenseRequest to license server, and the agreement and the communication of algorithms according to the version of consulting send to license server to relevant information.
Step 140: license server is responded the request of client, informs client licence etc. by LicenseResponse.
Step 150: client is initiated to obtain to license server and is confirmed request LicenseConfirmRequest, has wherein comprised the reception installment state of licence sign and this licence.
Step 160: license server is responded the request of client, informs by LicenseConfirmResponse and confirms the processing of request state to obtaining.After server returned success response, client just can be used this licence; Otherwise client will be abandoned this licence.
Licence is cancelled agreement and is mainly comprised two message: LicenseConfirmRequest (licence confirm request) and LicenseConfirmResponse (licence is confirmed response) in the selected agreement described in the step 120, wherein:
Whether LicenseConfirmRequest message is sent to the license server end from client, be used for confirming successfully to receive and the installation license card to license server;
LicenseConfirmResponse message is sent to client from the license server end, the licence LicenseConfirmRequest request of customer in response end.
Form below by form is made description to the LicenseConfirmRequest message parameter in the step 150:
| Parameter | Whether optional |
| SessionID | M |
| CommunicationKey | M |
| CommunicationKeyEncryptAlgorithm | M |
| UserUUID | M |
| UserPassword | O |
| LicenseID | M |
| InstallStatus | M |
| ServerInfo | O |
| Extensions | O |
| HashAlgorithm | M |
| Signature | M |
| SignatureAlgorithm | M |
SessionID: identical with the SessionID in previous LicenseResponse (with LicenseRequest, the ServerLicHello) message, otherwise will stopping licence, server obtains agreement.
CommunicationKey: the ciphertext of the key that is used to communicate by letter that produces by client.
CommunicationKeyEncryptAlgorithm: the cryptographic algorithm of communication key, communication key use the PKI of server to encrypt.
UserUUID: user's identify label.
UserPassword: user cipher.
LicenseID: licence sign.
InstallStatus: the installment state of the licence that " LicenseID " identified: success or failure.
ServerInfo: be some information that are used for describing server.
Extensions: be to be used for describing some extend informations,, can define according to different situation oneself to the using and be defined in and do not have clear and definite regulation in this agreement of extend information.
HashAlgorithm: hashing algorithm, the hashing algorithm that uses when referring to sign.When message-length more in short-term, directly message is signed with signature algorithm, when message-length is long, before signature, message is carried out hash, the hashing algorithm of use is exactly this field appointment.
Signature: client sends the signature of message to him.
SignatureAlgorithm: signature algorithm.
