Description

Authentication method, server and client
Technical Field
The present application relates to the field of communications technologies, and in particular, to an authentication method, a server, and a client.
Background
In the prior art, when authenticating a service request packet, a server usually completes an authentication process for the service request packet. For example, the client may send a service request packet to the server, so that after receiving the service request packet, the server authenticates the service request packet through the access control rule, and if the access control rule has an authentication rule corresponding to the service request packet and the authentication rule indicates that the service request packet is allowed to be processed, it is determined that the service request packet is successfully authenticated; if the authentication rule indicates that the service request message is rejected to be processed, determining that the service request message fails to be authenticated; on the contrary, if the access control rule does not have the authentication rule corresponding to the service request message, if the authentication result of the service person request message cannot be determined, the service request message needs to be authenticated for the second time through the global control rule.
However, when the user equipment sends more service request messages, and each service request message corresponds to at least one model node, or only one service request message is sent, but the service request message includes more model nodes, if the authentication results of the service request messages or one service request message cannot be determined by the access control rule, the global control rule needs to be traversed for each model node in the content modules to authenticate the service request message, but this may cause a large load on the server, so that the processing efficiency of the service request message is low.

Detailed Description
The embodiment of the application can be applied to various communication systems, such as: in the following description, some terms in the present application are explained to facilitate understanding by a person skilled in the art, in a Global System for mobile communication (GSM) System, a Code Division Multiple Access (CDMA) System, a Wideband Code Division Multiple Access (WCDMA) System, a General Packet Radio Service (GPRS), a Long Term Evolution (LTE), a 5G communication System, or other systems that may appear in the future. It should be noted that, when the scheme of the embodiment of the present application is applied to a 5G system or other systems that may appear in the future, names of network devices and clients may change, but this does not affect implementation of the scheme of the embodiment of the present application.
Fig. 1 is a schematic view of an application scenario provided by an embodiment of the present application, where the authentication method provided by the present application may be applied to a network architecture of a server and a client, where one server may interact with one or more clients, and one client may correspond to one or more users. When the service request message is authenticated, each client can firstly send the service request message to be processed to the server, and the server can authenticate the service request message according to the access control rule and then authenticate the service request message of which the authentication result cannot be determined according to the global control rule, but the load of the server is larger, so that the processing efficiency of the service request message is lower.
Wherein, 1) the server is mainly used for maintaining the information data of the managed device and responding the request of the client, and reporting the management data to the client sending the request. And the server analyzes the data after receiving the request of the client, processes the request with the help of an internal Netconf framework, and then returns a response to the client.
2) The network management center of the whole network of the client mainly utilizes network management protocols such as NETCONF and the like to carry out system management on the network equipment.
3) "plurality" means two or more, and other terms are analogous. "and/or" describes the association relationship of the associated objects, meaning that there may be three relationships, e.g., a and/or B, which may mean: a exists alone, A and B exist simultaneously, and B exists alone. The character "/" generally indicates that the former and latter associated objects are in an "or" relationship.
In order to solve the problem that the processing efficiency of a service request message is low due to a large load of a server when the service request message is authenticated in the prior art, the embodiment of the application provides an authentication method, wherein in the authentication method, the server can firstly send a first indication message to a client; the first indication message comprises an identifier of each user associated with the client and an access control rule associated with each user, and the first indication message is used for indicating the client to authenticate the service request message to be processed through the access control rule; after authenticating the service request message to be processed according to the access control rule at the client, sending the service request message to be processed authenticated by the client through the access control rule to the server; the authenticated to-be-processed service request message is a successfully authenticated to-be-processed service request message and/or a to-be-processed service request message of which the authentication result cannot be determined, so that after the server receives the authenticated to-be-processed service request message, if the authenticated to-be-processed service request message is the successfully authenticated to-be-processed service request message, the server authenticates the authenticated service request message according to an access control rule; if the authenticated to-be-processed service request message is a successfully authenticated to-be-processed service request message and a to-be-processed service request message of which the authentication result cannot be determined, or if the authenticated to-be-processed service request message is a to-be-processed service request message of which the authentication result cannot be determined, the server authenticates the authenticated service request message sequentially according to the access control rule and the global control rule. Compared with the prior art, the server does not directly authenticate all the service requests to be processed, but sends the access control rules associated with the server to the client so that the client performs primary authentication according to the received access control rules, and only sends the service request messages to be processed which are successfully authenticated and/or the service request messages to be processed which can not determine the authentication result to the server, but does not send the service request messages to be processed which are failed in authentication.
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. For example, please refer to fig. 2, where fig. 2 is a schematic diagram of an authentication method provided in an embodiment of the present application, and the authentication method may include:
s201, a preset channel is established between the server and the client.
For example, in the embodiment of the present application, the preset pass may be a netconf session, that is, the server needs to establish a netconf session with the client first. For example, establishing the channel between the server and the client may include: the server sends a first hello message to the client; the first hello message comprises a newly-added distributed Netconf access control model capability set (named distributed-nacm capability set); receiving a second hello message sent by the client; the second hello message comprises a distributed Netconf Access Control Model (NACM) capability set (named distributed-NACM capability set); after determining that both the first hello message and the second hello message include the distributed NACM capability set, the server may establish a preset channel between the client and the NACM capability set included in the first hello message and the second hello message, and at this time, both the server and the client support distributed-NACM capability sets, so that the server may add an access control rule associated with a user in a first indication message (for example, a notification message) and send the notification message to the client through a Netconf session.
After the server establishes the preset channel with the client, the following S202 may be executed:
s202, the server sends a first indication message to the client through a preset channel.
The first indication message comprises the identification of each user associated with the client and the access control rule associated with each user, and the first indication message is used for indicating the client to authenticate the service request message to be processed through the access control rule.
Wherein, the access control rule is a Non-Global control rule (Non-Global control rules). It should be noted here that, when the server sends the first indication message to the client through the preset channel, the server may send only the identifier of each user associated with the client and the access control rule associated with each user to the client, so that after receiving the first indication message, the client saves the access control rule associated with each user, and executes the following S203:
s203, the client authenticates the service request message to be processed according to the access control rule to obtain the authenticated service request message to be processed.
The authenticated to-be-processed service request message is a successfully authenticated to-be-processed service request message and/or a to-be-processed service request message of which the authentication result cannot be determined.
In the embodiment of the present application, because the problem that the processing efficiency of the service request packet is low due to a large load of the server when the service request packet is authenticated in the prior art is considered, according to the authentication method provided in the embodiment of the present application, when the service request packet is authenticated, the server may first send the access control rule associated with each user to the client through the preset channel, so that the client may first authenticate the service request packet to be processed according to the access control rule when receiving the access control rule, thereby obtaining the service request packet to be processed after the first authentication.
Optionally, when the client authenticates the to-be-processed service request packet according to the access control rule, the client may first determine, according to the identifier of the user corresponding to the to-be-processed service request packet, an access control rule associated with the user in the access control rule; and then, according to the determined user-associated access control rule, authenticating the service request message to be processed. Further, when the service request message to be processed is authenticated according to the determined user-associated access control rule, if the authentication rule corresponding to the service request message to be processed exists in the user-associated access control rule and the authentication rule indicates that the service request message to be processed is allowed to be processed, the client determines that the authentication of the service request message to be processed is successful; or, if the access control rule associated with the user has an authentication rule corresponding to the service request message to be processed, and the authentication rule indicates that the service request message to be processed is not allowed to be processed, the client determines that the authentication of the service request message to be processed fails; or, if the authentication rule corresponding to the service request message to be processed does not exist in the access control rule associated with the user, the client cannot determine the authentication result of the service request message to be processed.
After the client authenticates the service request message to be processed for the first time according to the access control rule, the authentication result corresponding to each service request message to be processed can be obtained. For example, the authentication result may be authentication success, authentication failure, or failure to determine the authentication result. It should be noted that, in the embodiment of the present application, after obtaining the authentication result corresponding to each service request packet to be processed, not all the pending service request messages corresponding to the authentication result are sent to the server for secondary authentication, but only sends the successfully authenticated pending service request message and/or the pending service request message that cannot determine the authentication result to the server for secondary authentication, in other words, the pending service request that fails to be authenticated is not sent to the server again, thus, the server only needs to perform secondary authentication on the successfully authenticated pending service request message and/or the pending service request message for which the authentication result cannot be determined, and the to-be-processed service request message which fails to be authenticated does not need to be authenticated, so that the load of the server is reduced, and the processing efficiency of the service request message is improved.
After authenticating the service request message to be processed according to the access control rule and obtaining the authenticated service request message to be processed, the client may send the authenticated service request message to be processed to the server, so that the server performs secondary authentication on the authenticated service request message to be processed, that is, the following S204 is executed:
and S204, the client sends the service request message to be processed after the client is authenticated by the access control rule to the server.
The authenticated to-be-processed service request message is a successfully authenticated to-be-processed service request message and/or a to-be-processed service request message of which the authentication result cannot be determined.
S205, the server authenticates the authenticated service request message according to the access control rule.
After the server receives the service request message to be processed after the client is authenticated by the access control rule through the above S204, the server can authenticate the authenticated service request message according to the access control rule. It should be noted that, when the server authenticates the authenticated service request packet according to the access control rule, and when the authenticated to-be-processed service request packet is only a successfully authenticated to-be-processed service request packet, the server may authenticate the authenticated to-be-processed service request packet according to the access control rule only, so as to obtain an authentication result of the authenticated to-be-processed service request packet. When the authenticated to-be-processed service request message is a to-be-processed service request message for which the authentication result cannot be determined, the authenticated to-be-processed service request message may be authenticated according to an access control rule, and in general, the authentication result of the to-be-processed service request message according to the access control rule is the same as the authentication result of the to-be-processed service request message according to the access control rule of the client, so that after the server authenticates the authenticated to-be-processed service request message according to the access control rule of the server, the authentication result of the authenticated to-be-processed service request message still cannot be determined, and the authenticated to-be-processed service request message needs to be authenticated again according to the global control rule, thereby obtaining the authentication result of the authenticated to-be-processed service request message. When the authenticated to-be-processed service request message is a successfully authenticated to-be-processed service request message and a to-be-processed service request message for which the authentication result cannot be determined, the successfully authenticated to-be-processed service request message and the to-be-processed service request message for which the authentication result cannot be determined can be authenticated according to the access control rule of the server, under the normal condition, the authentication result of the to-be-processed service request message according to the access control rule of the server is the same as the authentication result of the to-be-processed service request message according to the access control rule of the client, so that after the successfully authenticated to-be-processed service request message and the to-be-processed service request message for which the authentication result cannot be determined are authenticated by the server according to the access control rule of the server, the successfully authenticated to-be-processed service request message can be obtained, and for the authentication result of the to-be-processed, the authenticated service request message to be processed needs to be authenticated again according to the global control rule, so as to obtain the authentication result of the authenticated service request message to be processed.
Optionally, after receiving the service request message to be processed authenticated by the client according to the access control rule, the server may determine, according to the user identifier corresponding to the authenticated service request message to be processed, the user group to which the user belongs according to the user identifier and the corresponding relationship between the user identifier and the user group; after determining the user group to which the user belongs, determining an access control rule corresponding to the user group to which the user belongs in an access control rule set according to the user group to which the user belongs and the corresponding relation between the user group and the access control rule; thus, after the access control rule corresponding to the user group to which the user belongs is determined, the server can determine the access control rule associated with the user in the access control rule corresponding to the user group to which the user belongs according to the identification of the user.
When the server authenticates the authenticated service request message according to the user-associated access control rule, the authentication method is similar to the method for authenticating the service request message to be processed by the client according to the user-associated access control rule, and herein, the embodiment of the present application is not repeated. After authenticating the authenticated service request message according to the access control rule associated with the user, if there is a service request message for which the authentication result cannot be determined, the server may authenticate the authenticated service request message according to the global control rule, specifically: if the global control rule indicates that the to-be-processed service request message of which the authentication result cannot be determined is allowed to be processed, the server determines that the to-be-processed service request message of which the authentication result cannot be determined is successfully authenticated; or, if the global control rule indicates that the to-be-processed service request message of which the authentication result cannot be determined is not allowed to be processed, the server determines that the authentication of the to-be-processed service request message of which the authentication result cannot be determined fails, so that the authentication result of the to-be-processed service request message of which the authentication result cannot be determined is obtained.
Therefore, according to the authentication method provided by the embodiment of the application, when the service request message to be processed is authenticated, the server can firstly send the access control rule associated with each user to the client, so that after the client receives the access control rule associated with each user, the service request message to be processed can be authenticated for the first time according to the access control rule, and the service request message to be processed, which is successfully authenticated and/or cannot determine the authentication result, obtained by the first authentication is sent to the server, so that the server can perform secondary authentication on the service request message after authentication according to the access control rule. Compared with the prior art, the server does not directly authenticate all the service requests to be processed, but sends the access control rules associated with the server to the client so that the client performs primary authentication according to the received access control rules, and only sends the service request messages to be processed which are successfully authenticated and/or the service request messages to be processed which can not determine the authentication result to the server, but does not send the service request messages to be processed which are failed in authentication.
Based on the embodiment shown in fig. 2, it should be further noted that when the client performs authentication according to the access authentication rule sent by the server, and when the access control rule at the server side changes, the server needs to notify the client of the updated access control rule, so as to avoid the client authenticating the service request packet to be processed by using the access control rule before updating, thereby improving the accuracy of the client authenticating the service request packet to be processed. For example, please refer to fig. 3, where fig. 3 is a schematic diagram of another authentication method provided in the embodiment of the present application, and the authentication method may further include:
s301, when the access control rule changes, the server sends a second indication message to the client.
The second indication message includes the identifier of each user and the updated access control rule associated with each user, and the second indication message is used for indicating the client to authenticate the service request message to be processed according to the updated access control rule.
For example, when it is determined that the access control rule changes, the identifier of each user and the updated access control rule associated with each user may also be added to the extended notification message and sent to the client through netconfession, and because the client also supports distributed-nacm capability set, the client may parse the notification message after receiving the notification message and store the updated access control rule associated with the user and included in the notification message, so as to perform authentication according to the updated access control rule, that is, the following S302:
s302, the client authenticates the service request message to be processed according to the updated access control rule.
Optionally, when the client authenticates the to-be-processed service request packet according to the updated access control rule, the client may first determine, according to the identifier of the user corresponding to the to-be-processed service request packet, the user-associated access control rule in the updated access control rule; and then, according to the determined user-associated access control rule, authenticating the service request message to be processed. Further, when the service request message to be processed is authenticated according to the determined updated access control rule associated with the user, if an authentication rule corresponding to the service request message to be processed exists in the updated access control rule associated with the user and the authentication rule indicates that the service request message to be processed is allowed to be processed, the client determines that the authentication of the service request message to be processed is successful; or, if the updated access control rule associated with the user has an authentication rule corresponding to the service request message to be processed, and the authentication rule indicates that the service request message to be processed is not allowed to be processed, the client determines that the authentication of the service request message to be processed fails; or, if the updated access control rule associated with the user does not have the authentication rule corresponding to the service request message to be processed, the client cannot determine the authentication result of the service request message to be processed, so as to obtain the authentication result corresponding to each service request message to be processed, and complete the first authentication of the service request message to be processed.
In addition, it should be noted that in the embodiment shown in fig. 2 or fig. 3, after the preset channel is established, the client may detect the current state of the preset channel in real time, and of course, the client may also detect the current state of the preset channel at intervals of a preset duration, and if the client determines that the preset channel is interrupted, the stored access control rule associated with each user may be deleted, so as to save the memory of the client.
