It will be understood by those skilled in the art that the present disclosure may be practiced without some of these specific details. In some instances, methods, means, elements and circuits that are well known to those skilled in the art have not been described in detail so as not to obscure the present disclosure.
Fig. 1 is a flow chart illustrating a method of identity authentication in accordance with an example embodiment. The identity authentication method of the embodiment can be applied to a broadband access server BRAS. As shown in fig. 1, the method includes:
step S11, under the condition that the BRAS and the client are in three-layer connection and the client meets the identity authentication condition, the IP address of the client carried in the message sent by the client is obtained;
step S12, obtaining the mapping pair of the client IP address and the MAC address from the DHCP server;
step S13, acquiring the MAC address of the client based on the IP address and the mapping pair.
According to the embodiment of the disclosure, when the BRAS is connected with the client in three layers and the client meets the identity authentication condition, the client IP address carried in the message sent by the client is acquired, and the MAC address of the client is acquired based on the mapping between the client IP address and the MAC address, so that the MAC identity authentication request is automatically performed, the authentication information is prevented from being manually input by a user, and the non-perception authentication of the user during internet surfing is realized. According to the embodiment of the disclosure, the networking requirement between the authentication client and the BRAS during the deployment of the unaware scheme can be reduced, and the two-layer networking connection and the three-layer networking connection are compatible, so that the scheme deployment is easier, and the user experience is improved.
Fig. 2 is a schematic diagram illustrating an application scenario of an identity authentication method according to an exemplary embodiment. As shown in fig. 2, the broadband access server BRAS22 may establish a communication connection with a DHCP (Dynamic Host Configuration Protocol) server 25. The DHCP server 25 is configured to dynamically allocate network configuration parameters such as an IP address to the network device. The DHCP server 25 uses a client/server communication mode, the client applies for requesting allocation of network configuration parameters to the server, and the server returns configuration information such as an IP address allocated to the client, so as to implement dynamic configuration of information such as the IP address. The DHCP server 25 may also be a built-in DHCP server on the BRAS22 or a DHCP relay (DHCP relay) closest to the client, which is not limited in this disclosure.
Fig. 3 is a flow chart illustrating a method of identity authentication in accordance with an example embodiment. The identity authentication method of the embodiment can be applied to a broadband access server BRAS. As shown in fig. 3, the method further comprises:
step S14, responding to the network communication request of the client, applying for IP address from the DHCP server;
step S15, when the application for IP address to DHCP server is successful, the mapping pair of the client IP address and MAC address from the DHCP server is saved locally in BRAS,
wherein, step 12 may comprise: the mapping pairs are read locally from the BRAS.
For example, when a user accesses a network through the client 21, the client 21 may initiate a network communication request. In response to a network communication request of the client 21, the BRAS22 may apply for the IP address of the client 21 from the DHCP server 25. For example, based on the access information (e.g., interface) of the client 21, the BRAS22 may find the domain (domain) corresponding to the client 21; according to the domain corresponding to the client 21, the BRAS22 can find the corresponding DHCP server 25, so that the IP address of the client 21 can be applied from the DHCP server 25.
In one implementation, after the DHCP server 25 successfully allocates an IP address to the client 21, the DHCP server 25 may record a mapping pair of the IP address of the client 21 and the MAC address of the client 21, and the DHCP server 25 may send the mapping pair to the BRAS 22. BRAS22 may check whether DHCP server 25 is a DHCP server of the domain corresponding to client 21 according to its own configuration. If DHCP server 25 is the DHCP server of the domain corresponding to client 21, BRAS22 may locally save the mapping pair from DHCP server 25; if DHCP server 25 is not the DHCP server of the domain corresponding to client 21, the message in which the mapping pair is located may be discarded. In this way, only the mapping pairs sent from the DHCP server of the domain corresponding to the client 21 can be saved, thereby reducing the storage pressure.
In one implementation manner, when the network access traffic of the client 21 reaches a certain threshold within a certain time, the client 21 may be considered to satisfy the identity authentication condition, and the identity authentication may be performed on the client 21. BRAS22 may obtain the MAC address of client 21 to initiate a MAC Authentication request to AAA (Authentication, Authorization, Accounting) Authentication server 24 based on the MAC address of client 21. The AAA authentication server 24 provides three network security management functions, namely authentication, authorization and accounting. And (3) authentication: confirming the identity of a remote user accessing the network, and judging whether an accessor is a legal network user; authorization: different authorities are given to different users, and the services which can be used by the users are limited. For example, an administrator authorizes an office user to access and print a file in the server, while other temporary visitors do not have this permission; charging: all operations of the user in the process of using the network service are recorded, including the type of the used service, the starting time, the data flow and the like, so that the use condition of the user on the network resource is collected and recorded, the charging requirement for the time and the flow can be realized, and the network is also monitored.
In one implementation, if there is three-layer connection between the BRAS22 and the client 21, the SMAC address in the message sent by the client 21 is the MAC address of the upper-layer router, so that the MAC address of the client 21 cannot be directly found; the SIP address in the message sent by the client 21 is the IP address of the client 21. Therefore, BRAS22 can obtain the IP address (SIP address) of client 21 carried in the message sent by client 21. Thus, BRAS22 can locally read the mapping pair and look up the mapping pair based on the IP address of client 21, so as to find out the MAC address of client 21.
In one implementation, when the AAA authentication server 24 receives the MAC identity authentication request from the BRAS22, it may determine whether the MAC address of the client 21 is a MAC address that has been bound to the user authentication information. If the MAC address of the client 21 is the MAC address bound with the user authentication information, the BRAS22 may be notified that the MAC identity authentication request passes, the BRAS22 may pass the network communication request of the client 21, and the user may normally surf the internet through the client 21.
By the mode of the embodiment of the disclosure, the mapping pair of the client IP address and the MAC address from the DHCP server can be locally stored in the BRAS, and the MAC address of the client is obtained based on the IP address and the mapping pair, so that MAC identity authentication is performed, authentication information input by a user is avoided, and non-perception authentication when the user accesses the Internet is realized, thereby improving user experience.
On the contrary, when the identity authentication is performed according to the related technology, the mapping pair of the client IP address and the MAC address is not stored in the BRAS, so that when three layers of connection are formed between the BRAS and the client, the BRAS cannot acquire the MAC address of the client, which results in failure of a MAC identity authentication request, and a user needs to input authentication information, which cannot realize the non-perception authentication, resulting in poor user experience.
Fig. 4 is a flowchart illustrating step 12 of a method of identity authentication according to an example embodiment. The identity authentication method of the embodiment can be applied to a broadband access server BRAS. As shown in fig. 4, step 12 may include:
step S121, sending an inquiry request of the mapping pair of the client IP address and the MAC address to a DHCP server;
step S122, receiving the mapping pair from the DHCP server.
For example, when a user accesses a network through the client 21, the client 21 may initiate a network communication request. In response to a network communication request of the client 21, the BRAS22 may apply for the IP address of the client 21 from the DHCP server 25. For example, based on the access information (e.g., interface) of the client 21, the BRAS22 may find the domain (domain) corresponding to the client 21; according to the domain corresponding to the client 21, the BRAS22 can find the corresponding DHCP server 25, so that the IP address of the client 21 can be applied from the DHCP server 25.
In one implementation, after the DHCP server 25 successfully allocates an IP address to the client 21, the DHCP server 25 may record a mapping pair of the IP address of the client 21 and the MAC address of the client 21, but not send the mapping pair to the BRAS 22.
In one implementation manner, when the network access traffic of the client 21 reaches a certain threshold within a certain time, the client 21 may be considered to satisfy the identity authentication condition, and the identity authentication may be performed on the client 21. BRAS22 may obtain the MAC address of client 21 to initiate a MAC authentication request to AAA authentication server 24 based on the MAC address of client 21.
In one implementation, if there is three-layer connection between the BRAS22 and the client 21, the SMAC address in the message sent by the client 21 is the MAC address of the upper-layer router, so that the MAC address of the client 21 cannot be directly found; the SIP address in the message sent by the client 21 is the IP address of the client 21. Therefore, BRAS22 may obtain the IP address (SIP address) of client 21 carried in the message sent by client 21, and send a query request of mapping pair of client IP address and MAC address to DHCP server 24.
In one implementation, DHCP server 25 may send a mapping pair of client IP address and MAC address to BRAS22 in response to a query request from BRAS 22. Upon receiving the mapping pair, BRAS22 may look up a match for the mapping pair from DHCP server 25 based on the IP address of client 21, and may match to the MAC address of client 21.
In one implementation, when the AAA authentication server 24 receives the MAC identity authentication request from the BRAS22, it may determine whether the MAC address of the client 21 is a MAC address that has been bound to the user authentication information. If the MAC address of the client 21 is the MAC address bound with the user authentication information, the BRAS22 may be notified that the MAC identity authentication request passes, the BRAS22 may pass the network communication request of the client 21, and the user may normally surf the internet through the client 21.
By means of the method and the device, the mapping pair query request can be sent to the DHCP server to obtain the mapping pair when the identity authentication condition is met, the MAC address of the client side is obtained based on the IP address and the mapping pair, the MAC identity authentication is convenient to carry out, the user is prevented from inputting authentication information, the non-perception authentication of the user during internet surfing is realized, and the user experience is improved.
On the contrary, when the identity authentication is performed according to the related technology, the BRAS cannot send a mapping pair query request to the DHCP server to acquire a mapping pair, so that when three layers of connection are formed between the BRAS and the client, the BRAS cannot acquire the MAC address of the client, which results in failure of the MAC identity authentication request, the user needs to input authentication information, and the unaware authentication cannot be realized, which results in poor user experience.
In one implementation, when the AAA authentication server 24 receives the MAC identity authentication request from the BRAS22, it may determine whether the MAC address of the client 21 is a MAC address that has been bound to the user authentication information. If the MAC address of the client 21 is not the MAC address bound with the user authentication information, the AAA authentication server 24 may determine that there is no MAC binding, and for the first time the client 21 accesses the internet, may notify the BRAS22 that the MAC identity authentication request fails (fails), and the BRAS22 does not pass the network communication request of the client 21.
In this case, if the user accesses an arbitrary Web address through a browser, the BRAS22 may redirect to the Portal Web page (Web) server 23 and transmit the MAC address of the client 21 to the Portal Web page server 23. The Portal web server 23 may pop up an authentication page in the web page of the browser for the user to enter user authentication information (e.g., username and password, etc.). Where redirection may refer to redirection of the client's 21 network request (access to any web site) to another network location (the authentication page of the Portal web server 23). After the user inputs and confirms the user authentication information on the authentication page, the Portal web server 23 may send the user authentication information of the client 21 and the MAC address from the BRAS22 to the AAA authentication server 24, and initiate a MAC identity authentication request to the AAA authentication server 24.
In one implementation manner, the AAA authentication server 24 may verify the user authentication information, and if the user authentication information passes the verification, determine the MAC address of the client 21 as the MAC address bound to the user authentication information, and notify the BRAS22 that the MAC authentication request passes, and the BRAS22 may pass the network communication request of the client 21, so that the user may normally surf the internet through the client 21. If the user authentication information is not verified (for example, the password is wrong), the BRAS22 is informed that the MAC identity authentication request fails, and the BRAS22 does not release the network communication request of the client 21.
It should be understood by those skilled in the art that the above-mentioned processing procedure after the MAC identity authentication request fails can be implemented by various methods known in the related art, and the disclosure is not limited thereto.
Fig. 5 is a flow chart illustrating a method of identity authentication in accordance with an example embodiment. The identity authentication method of the embodiment can be applied to a broadband access server BRAS. As shown in fig. 5, the method further comprises:
step S16, when receiving the notice message that the DHCP server releases the IP address, the mapping pair is deleted from BRAS locally.
For example, in the case where the BRAS22 locally stores the mapping pair of the client IP address and the MAC address from the DHCP server 22, if the DHCP server 25 releases the IP address assigned to the client 21, the DHCP server 25 may assign a new IP address when the client 21 accesses again. In this case, the correspondence (mapping pair) between the IP address and the MAC address of the client 21 changes, and the MAC address of the client 21 cannot be searched for from the mapping pair stored in the BRAS 22. At this time, the DHCP server 25 may send a notification message to the BRAS22 when the IP address is released, notifying that the IP address has been released. Thus, BRAS22 can remove the mapping pair from local.
In this way, invalid mapping pairs can be deleted, reducing storage pressure.
Fig. 6 is a flow chart illustrating a method of identity authentication in accordance with an example embodiment. The identity authentication method of the embodiment can be applied to a DHCP server. As shown in fig. 6, the method includes:
step S61, responding to the client IP address distribution request from the broadband access server BRAS, and distributing the IP address for the client;
and step S62, under the condition that the IP address is successfully allocated to the client, sending the mapping pair of the IP address and the MAC address of the client to the BRAS, so that the BRAS acquires the MAC address of the client based on the mapping pair.
For example, as shown in fig. 2, when a user accesses a network through a client 21, the client 21 may initiate a network communication request. In response to a network communication request of the client 21, the BRAS22 may apply for the IP address of the client 21 from the DHCP server 25. DHCP server 25 may assign an IP address to client 21 in response to a client IP address assignment request from BRAS 22.
In one implementation, in the case of successful allocation of an IP address to the client 21, the DHCP server 25 may send a mapping pair of the IP address and the MAC address of the client 21 to the BRAS. Thus, when the BRAS22 and the client 21 are connected in three layers and the client 21 meets the authentication condition, the BRAS22 can obtain the MAC address of the client based on the mapping pair, and further initiate a MAC authentication request to the AAA authentication server 24.
In one implementation, step S62 may include: in response to a query request of a BRAS for a mapping pair of a client IP address and a MAC address, sending the mapping pair to the BRAS so that the BRAS acquires the MAC address of the client based on the mapping pair. For example, after the DHCP server 25 successfully allocates the IP address to the client 21, the DHCP server 25 may record a mapping pair of the IP address of the client 21 and the MAC address of the client 21. When the client 21 satisfies the authentication condition, the BRAS22 may send a query request of a mapping pair of the client IP address and the MAC address to the DHCP server 24. DHCP server 25 may send the mapping pair to the BRAS in response to the query request, so that the BRAS obtains the MAC address of the client based on the mapping pair.
In one implementation, the method may further include: and when the IP address is released, sending a notification message to the BRAS. For example, in the case where the BRAS22 locally stores the mapping pair of the client IP address and the MAC address from the DHCP server 22, if the DHCP server 25 releases the IP address assigned to the client 21, a notification message may be sent to the BRAS22 to notify that the IP address has been released. Thus, BRAS22 can remove the mapping pair from local.
According to the embodiment of the disclosure, the IP address can be allocated to the client, and the mapping pair of the IP address and the MAC address of the client is sent to the BRAS, so that the BRAS acquires the MAC address of the client based on the mapping pair, thereby carrying out MAC identity authentication, avoiding the manual input of authentication information by a user, and realizing the non-perception authentication when the user accesses the Internet.
