Description
Technical field
The present invention relates to computer network communication field, in particular to a kind of authentication method of message and device, certificate server.
Background technology
Along with the large-scale application of 802.1X authentication, the authenticated scale increases rapidly, and authentication performance becomes a characteristic that urgency is to be hoisted gradually, and various solutions also begin to occur, and in correlation technique, main solution has following several kinds:
1, hardware lift method: this method is set about from certificate server hardware; The various hardware of upgrade server; Comprise central processor CPU, internal memory, hard disk; Make the authentication processing performance of certificate server be highly improved, generally this method is applied to the more situation of the shared hardware resource of authentication software system.Shortcoming is that the hardware lifting also is that the limit is arranged, and the lifting to authentication performance after reaching the limit of also has been to the end.
2, information cache method: under the situation that server hardware promotes; Authentication performance has obtained interim lifting; But often still be because information is read and write from hard disk and caused whole authentication performance still not ideal enough; What occur under these circumstances is exactly the information cache method, and the information that need read and write authentication no longer stores in the hard disk, but in running, all is cached to the information of needs in the internal memory; The direct read hard disk can be avoided fully like this, often the authentication processing performance can be promoted significantly.Defective is if behind information cache, still can't reach the requirement of authentication performance, has not then had solution.The method for caching information of correlation technique is described below:
(the Remote AuthenticationDial In User Service of remote customer dialing authentication system under the 1x authentication system; Abbreviating Radius as) certificate server is mainly used in and receives the message identifying and book keeping operation message that the authentication access device sends; The handling property of Radius server will directly have influence on the use experience of authenticated; Here do not discuss and how to make the performance of Radius certificate server best; But provide a kind of simple effective method to make that the Radius authentication performance is more effective to the performance bottleneck of certain the special link under certain application-specific pattern in the Radius verification process, avoid unnecessary authentication performance expense.
Wherein, the application model that is directed against has following characteristic: reciprocal process requires to respond; Requirement has retransmission mechanism; Retry interval and number of times restriction.
The purpose of this application model mainly is in order to make whole authentication process more reliable; Necessarily require server that response is arranged, and the carrying out that does not obtain in the certain intervals responding repeatedly retransmitted, but can there be some problem in this pattern; For example when server performance is relatively good; Require response and retransmission mechanism to make authentication more reliable, but when server performance becomes slowly owing to various factors, retransmission mechanism will cause server performance to waste.
Correlation technique is in order to obtain more effective performance at present, and general common solution comprises following four kinds: hardware layer uses high-performance server and memory device; Network layer is carried out VLAN (Virtual Local Area Network abbreviates VLAN as) to the Radius server and is isolated; Software layer uses multithreading; The buffering area Design Mode.
More than four kinds of methods can promote the performance of certificate server really; But no matter how the performance of server improves; Always can't avoid in running, causing decreased performance, add superincumbent application model, the very possible state that wastes that forms of server owing to various factors.
To preceding text decreased performance problem, the optimization method to the buffering area design is proposed under a kind of prerequisite of application characteristic in the above.
Fig. 1 is a sketch map of handling message according to correlation technique certificate server performance when good; Fig. 2 is a sketch map of handling message during according to correlation technique certificate server poor performance.
As depicted in figs. 1 and 2, according to authentication performance a suitable buffer size is set, be N/second such as authentication performance; Buffer size is typically provided to N so; The flexible point of doing can provide configurable mode, can be according to the situation of reality, like hardware performance; Memory property waits self-defined setting, to satisfy different application; But there is a defective in this scheme: because buffering area is fixed, message is dropped when message is many, and the message that abandons is asked to retransmit, even but the message server that retransmits carried out responding and also be dropped, wasted the performance of server; The authentication performance of server is not what be completely fixed in actual environment, and along with long operation or receive under the situation of network attack, it is very poor that the performance of certificate server can become; Under the situation that retransmission mechanism is arranged and require to respond, retransmission mechanism can cause server performance in time to be alleviated, and is much overtime in message message reality when handling of buffering area; Server is the processing overtime file in time; Cause the invalidation of message, server is in one and wastes state, but also causes the message identifying of authentication afterwards also can't in time be handled; Can cause the authentication difficulty in this case, become a bottleneck of server performance.
Disposed overtime repeating transmission such as access device, timeout interval is 3 seconds, and then message is after issuing server; The response that in 3 seconds, does not obtain certificate server just retransmits, and retransmits at most 3 times, because buffering area is fixed; Here retransmit and make server will handle more request message, even and if retransmit the original message in back afterwards server carried out responding and also think invalid packet and abandon, under such situation; Server will be handled the timeout packet that more need not handled; Cause server message treatment effeciency to reduce, cause switch to retransmit the increase of message amount conversely, cause the more invalid timeout packet processing of server again; Final formation vicious circle makes the server message processing capability greatly reduce even has no effective message to handle; Under the extreme case, all messages are all overtime, and all processing are also just invalid.
Fig. 3 is the flow chart according to the authentication processing of the message of correlation technique.As shown in Figure 3, this method may further comprise the steps:
Step S301, switch send authentication request packet to certificate server; Step S303, certificate server receives message and deposits message buffer in, and this buffering area is a fixed value; Step S305, certificate server take out message and handle and respond from buffering area, give switch with the result.
3, authentication load balancing method: after having carried out hardware lifting and information cache, if still can't satisfy the demand of authentication performance, people have gradually used the method for authentication load balancing to promote performance; Be exactly that the thing done of original 1 certificate server is used two in simple terms; Three even extendible n platform are done, and doing like this can avoiding method 1 and the shortcoming of method 2: do not have bottleneck, can infinitely promote performance in theory; But cost is higher, and stability does not ensure.
When handling message, often formation wastes state, and then causes the lower problem of server process efficient, does not propose effective solution at present as yet to server in the correlation technique.

(the Remote Authentication Dial In UserService of remote customer dialing authentication system; Abbreviate Radius as); Be a kind of between network access server (Network AccessServer, be called for short NAS) and shared certificate server the agreement of certified transmission, mandate and configuration information.Radius uses UDP (User Datagram Protocal abbreviates UDP as) as its host-host protocol.Radius also is responsible for transmitting the charge information between network access server and shared accounting server in addition.
Radius has following principal character:
The Client/Serve pattern: network access server is responsible for user profile is passed to the Radius server of appointment as the client of Radius, operates according to return information then.The Radius server is responsible for receiving user's connection request, after the authenticated, returns the configuration information that is necessary so that client provides service for the user.The Radius server can be used as the agency of other Radius servers or certificate server.
Network security: communicating by letter between client and the Radius server is to be used for differentiating that through sharing making of key this shared key can not transmit through network.In addition, the Any user password all need carry out ciphering process when between client computer and Radius server, sending, and can obtain user cipher to have avoided the people through smelling the spy unsecured network.
Flexible authentication mechanism: the Radius server is supported multiple user authen method.After the user provided user name and original password, the Radius server can be supported PPP PAP or CHAP, UNIX login and other authentication mechanism.
Switch is overtime: switch is as the client of Radius; The Radius message that it sends to server necessarily requires to respond within a certain period of time; Otherwise it will think that this message is overtime, send to the message of server before then can retransmitting, and then no longer wait for for the message of original transmission (just meaning after overtime; Even if server is handled this timeout packet and is responded; Switch can not handled this back message using yet, and in this case, server is exactly invalid to the processing and the response of timeout packet).
The Radius certificate server is mainly used in and receives the message identifying and book keeping operation message that the authentication access device sends under the 1x authentication system; The handling property of Radius server will directly have influence on the use experience of authenticated; Here do not discuss and how to make the performance of Radius certificate server best; But provide a kind of simple effective method to make that the Radius authentication performance is more effective to the performance bottleneck of certain the special link under certain application-specific pattern in the Radius verification process, avoid unnecessary authentication performance expense.
