It should be understood that the terms first, second, etc. in the description of the embodiments of the present application are used for distinguishing between the descriptions and not for indicating or implying relative importance or order. In the description of the embodiments of the present application, "a plurality" means two or more.

The term "and/or" in the embodiment of the present application is only one kind of association relationship describing an associated object, and means that three kinds of relationships may exist, for example, a and/or B may mean: a exists alone, A and B exist simultaneously, and B exists alone. In addition, the character "/" herein generally indicates that the former and latter related objects are in an "or" relationship.

In order to facilitate understanding of the scheme of the embodiment of the present application, a possible application scenario of the embodiment of the present application is described below.

Referring to fig. 1a, which is a schematic diagram of a network topology applicable to the embodiment of the present application, the diagram shows a network topology of a network maintenance area. Specifically, in the network topology shown in fig. 1a, four MEPs are included, namely: MEP001, MEP002, MEP003, MEP004, any two MEPs may communicate with each other in a wired or wireless manner. Ethernet OAM is deployed in each MEP, and the technical scheme of the embodiment of the application can be realized by operating the Ethernet OAM by each MEP. It should be understood that fig. 1a is only an example, and in actual production life, there may be a greater number or a smaller number of MEPs in a network maintenance area, and the application is not limited thereto.

In the method provided in this embodiment of the present application, a network Maintenance area may further include a Maintenance Identity Authentication node (MIAP) for providing registration for multiple MEPs in the network Maintenance area, that is, the MIAP in fig. 1 a.

Referring to fig. 2, a flowchart of a registration method provided in an embodiment of the present application may be applied to the scenario shown in fig. 1a, where the method specifically includes:

step S201: the first MEP sends the equipment information and the public key of the first MEP to the MIAP, and the MIAP acquires the equipment information and the public key of the first MEP.

Where the first MEP is any other MEP in the same network maintenance area that is capable of communicating with the MIAP. For example, the first MEP is MEP001 or MEP002 as shown in fig. 1 a.

It should be understood that, in the same network maintenance area, there may also be a second MEP, a third MEP, a fifth MEP, and the like, and these MEPs may implement the same function as the first MEP in the solution of the present application, and the present solution may also be applied to all MEPs in other MEPs belonging to the same network maintenance area as the MIAP at the same time, which is not limited in the present application. For example, in step S201, the MIAP may acquire the device information and the public key of the first MEP, the MIAP may acquire the device information and the public key of the second MEP or the third MEP, or the MIAP may simultaneously acquire the device information and the public key of all other MEPs in one network maintenance area, such as the first MEP, the second MEP, and the third MEP.

Optionally, when the MIAP acquires the device information and the public key of the first MEP, the MIAP may send the first notification information to the multiple MEPs in the network maintenance area where the MIAP is located in a multicast manner, where a destination address of the multicast corresponds to all MEPs in the network maintenance area where the MIAP is located; the first notification information is used to instruct the MEP receiving the first notification information to return the device information and the public key of the MEP to the MIAP.

Of course, the MIAP may also adopt other transmission manners, for example, unicast the first notification message to each other MEP through a preset address list, or transmit the first notification message in a broadcast manner, and so on.

When the first MEP receives the first notification information from the MIAP, the first MEP returns its own device information and public key to the MIAP in response to the first notification information, and the first MEP may itself maintain a private key opposite to the public key. The public key may be a public key in a pair of asymmetric keys generated by the first MEP in response to the first notification information after the first MEP receives the first notification information, or may be generated in advance by the first MEP and stored in the first MEP, which is not limited in this application.

By the method, the MIAP directly acquires the equipment information and the public key of other MEPs, and can quickly finish information collection of other MEPs in the same network maintenance area.

Alternatively, different MEPs in a network maintenance area may have different levels.

Further, an MEP at a high level may send a message to an MEP at a low level or to an MEP at the same level.

For the MIAP, the MIAP may receive messages of all levels of MEPs in the same network maintenance area, which corresponds to the lowest level of the MIAP in the same network maintenance area. However, the first notification information is sent at the MIAP, and the level of the first notification information is the same as the level of the MEP at the highest level in the network maintenance area, so as to ensure that all MEPs in the network maintenance area can receive the first notification information sent by the MIAP. And when the MIAP receives the messages sent by other MEPs and sends corresponding messages to other MEPs, the level of the corresponding messages is equal to the level correspondence of other MEPs.

For example, referring to fig. 1b, in another possible network topology structure diagram provided by the present application, in the scenario shown in fig. 1b, all MEPs in a network maintenance area are assigned with different levels, for example, the level of a first MEP and a second MEP is level 1, and the level of a third MEP and a fourth MEP is level 3. Depending on the ranking of the MEPs, the MEPs may be divided into different MEG. It should be understood that the number and the levels of the MEPs in fig. 1b are only examples, in actual production life, there may be a greater number or a smaller number of levels (i.e., MEG) in a network maintenance area, and there may also be a greater number or a smaller number of MEPs in an MEG, and the present application is not limited thereto.

For example, in fig. 1b, when the MIAP sends the first notification information, the level of the first notification information is level 3, so that it is ensured that all of the first, second, third, and fourth MEPs can receive the first notification information. And when the MIAP needs to return feedback information to the first MEP after receiving the message sent by the first MEP, the level of the feedback information is the same as that of the first MEP.

In the method, different MEPs are positioned at different levels, and the messages sent by the MEPs are only received by the fixed levels, so that the efficiency of network communication is improved. The message sent by the MIAP can be received by all MEPs in the same MEG, and the MIAP can also receive the message sent by all MEPs in the same MEG.

Step S202: and the MIAP verifies the validity of the identity of the first MEP based on the acquired equipment information of the first MEP.

In one possible embodiment, the MIAP is only responsible for collecting the device information and public key of the first MEP, and the verification of the validity of the MEP identity is done by the network administrator.

Specifically, after the MIAP collects the device information of the first MEP, the device information of the first MEP is displayed in a human-computer interaction interface, and a network manager judges whether the identity of the first MEP is legal. If the network administrator determines that the identity of the first MEP is legal, a first instruction is input to indicate that the identity of the first MEP is legal; if the network administrator determines that the identity of the first MEP is not legal, a second instruction is input to indicate that the identity of the first MEP is illegal. Optionally, the operation of inputting the instruction may be completed on the human-computer interaction interface, or may be completed on other interfaces.

Illustratively, the MIAP displays the collected device information of the first MEP on the display device, and the network administrator determines whether the identity of the first MEP is legal according to the displayed device information of the first MEP, such as the manufacturer information of the device, the Media Access Control (MAC) address, the MEP number, and other information. For example, the network administrator knows the device information of all the security devices in the network maintenance area, so the network administrator can compare the collected device information of the first MEP with the device information of all the security MEPs in the network maintenance area to determine whether the first MEP is legal or not. If the first MEP is legal, the network administrator can enable the MIAP to receive the verification message by inputting an instruction, so as to indicate that the identity of the first MEP is legal.

In the method, the validity of the identity of the first MEP is verified in a manual auditing mode, so that the accuracy in identity verification is improved.

In another possible implementation, the MIAP directly checks the validity of the identity of the first MEP by determining whether the collected device information of the first MEP meets a preset rule.

Specifically, referring to fig. 3, a flowchart of a method for verifying the validity of the identity of the first MEP by the MIAP is provided in the embodiment of the present application, and the method includes the following specific steps:

s301: the MIAP receives device information of the first MEP.

S302: the MIAP judges whether the equipment information accords with a preset rule or not according to the received equipment information of the first MEP; if yes, go to step S303a, otherwise go to step S303 b.

The preset rule may be an audit rule pre-stored in the MIAP, for example, the preset rule may be a MAC address white list, and when the MAC address of the first MEP is in the white list in the device information of the first MEP received by the MIAP, the MIAP determines that the device information of the first MEP meets the preset rule, that is, the identity of the first MEP is legal. Or, the preset rule may also be an MEP white list established according to an MEP number in the device information or information of a manufacturer.

S303 a: the MIAP stores the device information for the first MEP in a database.

S303 b: the MIAP discards the device information of the first MEP.

Through the mode, the MIAP directly judges whether the identity information of the first MEP is legal or not according to the preset rule, and the efficiency of checking the identity of the first MEP is improved.

Optionally, referring to fig. 4, before executing step S303b, the MIAP may further select to take the following actions on the first MEP that does not satisfy the preset condition:

s401: judging whether the first MEP is an MEP in a blacklist or not according to the equipment information of the first MEP; if so, step S303b is executed directly, and if not, step S402 is executed.

The blacklist includes device information of a part of malicious MEPs, and the blacklist can be input to the MIAP in advance by a network manager or can be obtained by recording of the MIAP.

S402: and displaying the equipment information of the first MEP to a network manager through a man-machine interaction interface.

S403: receiving a verification message and judging the received verification message; if the received verification message is the first verification message, go to step S303 a; if the received authentication message is the second authentication message, step S404 is executed.

S404: the device information of the first MEP is saved in a blacklist.

After the recording is completed, step S303b may be performed.

Through the mode, the method combines the advantages of a direct judgment method and a manual auditing method, the MIAP directly audits the identities of other MEPs, the identities which meet the preset rule can be directly identified as legal, the identities which do not meet the preset rule can be continuously judged, the manual auditing is further carried out, the accuracy of identity auditing is ensured, and the auditing efficiency is improved. Moreover, the equipment information of the MEP which does not pass the audit is stored in the blacklist, so that the subsequent audit process is simplified, and the audit efficiency is further improved.

S203: and saving the equipment information and the public key of the first MEP which passes the verification.

Optionally, the device information and the public key may also be stored in other forms of data sets, such as in a file or in a table or in some documents.

S204: the MIAP generates a symmetric key and encrypts the symmetric key with the public key of the first MEP.

S205: the MIAP sends first encryption information to the first MEP, wherein the first encryption information comprises an encrypted symmetric key; the first MEP receives first encryption information.

S206: the first MEP responds to the first encryption information and sends feedback information to the MIAP; the MIAP receives the feedback information.

Optionally, after receiving the first encryption information, the first MEP sends feedback information to the MIAP by the following method: firstly, a first MEP decrypts first encryption information through a private key of the first MEP to obtain a symmetric key generated by an MIAP; secondly, the first MEP performs hash calculation on the symmetric key to obtain a first hash value; and finally, the first MEP sends feedback information to the MIAP, wherein the feedback information comprises a first hash value. Optionally, the first hash Value may be included in the feedback information in the form of a Type Length Value (TLV).

S207: the MIAP judges whether the first MEP successfully receives the symmetric key or not according to the feedback information; if it is determined that the first MEP is successfully received, step S208a is performed; if it is determined that the first MEP is not successfully received, step S208b is performed.

Optionally, the MIAP determines whether the first MEP successfully receives the symmetric key by:

first, the MIAP obtains a second hash value. The obtaining mode of the second hash value may include the following two modes: after receiving the feedback information, the MIAP directly performs Hash calculation on the symmetric key to obtain the symmetric key; the MIAP is directly obtained from the database, and the hash value stored in the database is obtained by directly carrying out hash calculation on the symmetric key when the MIAP generates the symmetric key and is stored.

Secondly, the MIAP compares the first hash value with the second hash value, and if the first hash value and the second hash value are consistent, the first MEP is confirmed to successfully acquire the symmetric key; and if the two are determined to be inconsistent, confirming that the first MEP fails to acquire the symmetric key.

By the method, the MIAP judges whether the first MEP successfully obtains the symmetric key or not through the Hash value, and the reliability of the scheme is improved.

S208 a: the MIAP marks the first MEP as a MEP with successful registration.

The successfully registered identifier may be stored in the database separately, or may be associated with the device information of the first MEP, which is not limited in this application.

S208 b: the MIAP marks the first MEP as a registration-failed MEP.

In the method, in a network maintenance area, the MIAP verifies the identities of other MEPs (such as the first MEP), so that the defect of authentication of the MEP identities, which is lack in the function of Ethernet OAM, is overcome. And the MIAP sends the symmetric key for communication to the MEPs passing the verification, thereby providing a verification foundation for the communication between the MEPs in the network maintenance area and improving the security of the communication between the MEPs. And registering the successful MEP by the mark of the successfully received MEP, and finishing the registration of the MEP. By the method, the function of performing identity authentication and registration on the MEP can be added in the Ethernet OAM, the management on the MEP can be effectively improved, and the security level of the Ethernet OAM is improved.

Optionally, after the MIAP determines that the first hash value is inconsistent with the second hash value, before executing step S208b, the MIAP may further send the first encryption information to the first MEP again for a preset number of times, where the preset number of times may be set according to an actual requirement, for example, may be set to 3 times; if the first hash value and the second hash value are not consistent after the predetermined number of times, step S208b is executed again.

Optionally, the communication between MEPs may add authentication information in the network maintenance area where registration is completed.

Specifically, the communication between the registered first MEP and the registered second and third MEPs will be described as an example.

When the first MEP sends the first transmission information to the second MEP, firstly, the first MEP needs to encrypt the transmission identification field through the symmetric key, and then perform hash calculation on the encrypted information to obtain a third hash value. Wherein, the transmission identification field is common information held by all MEPs in the same network maintenance area. Secondly, the first MEP sends the third hash value to the second MEP together with the first transmission information.

When the first MEP receives the second transmission information and the fourth hash value sent by the third MEP, first, the first MEP needs to determine whether the identity of the third MEP is legal or not according to the fourth hash value. Specifically, the first MEP encrypts the transmission field through the symmetric key, performs hash calculation on the encrypted information to obtain a fifth hash value, compares the fifth hash value with the fourth hash value, and if the fifth hash value and the fourth hash value are consistent, determines that the identity of the third MEP is legal, and receives the second transmission information; and if the first MEP identity and the second MEP identity are not consistent, the third MEP identity is determined to be illegal, and the second transmission information is discarded.

By the method, the first MEP can confirm whether the identity of the MEP of the opposite end is legal or not through the fourth hash value, and different methods are adopted for different identities, so that the communication safety between the MEPs is improved.

Optionally, the first transmission information and the second transmission information may be information for protection switching, or information for fault signal suppression, or information for controlling an opposite end MEP behavior.

Optionally, the MIAP periodically updates the symmetric key according to a preset time interval, and sends the updated symmetric key to all registered MEPs in a network maintenance area where the MIAP is located. The preset time interval may be set according to actual needs, for example, updated once every hour or updated not half an hour. The process of sending the updated symmetric key may specifically refer to the process of sending and confirming the symmetric key to the first MEP by the MIAP, which is not described herein again.

In this way, the MIAP periodically updates the symmetric key, which can effectively avoid the risk of possible disclosure caused by long-term use of the same symmetric key. Meanwhile, the MIAP only updates the symmetric key to the registered MEP, so that the MEP with unknown identity can be prevented from acquiring the symmetric key to invade the communication between the MEPs in the MEG, and the security level of the Ethernet OAM is improved.

Alternatively, when the MIAP receives a deregistration indication indicating deregistration of the first MEP, the MIAP may take the following response action.

In the first mode, the MIAP deletes the device information and the public key of the first MEP from the database.

The MIAP deletes the equipment information and the public key of the first MEP from the database; sending notification information to the first MEP, wherein the notification information is used for notifying that the first MEP is deleted; at the same time, the transmission of the updated symmetric key to the first MEP is stopped.

The MIAP deletes the equipment information and the public key of the first MEP from the database; stop sending the updated symmetric key to the first MEP and immediately update the symmetric key within the MEG.

By the method, a network manager can log out any MEP in the network maintenance area through the MIAP to complete the management of all MEPs in the network maintenance area. And when network management personnel find malicious MEPs, the network management personnel can process the MEPs in time, so that the security level of the Ethernet OAM is improved.

Optionally, the communication information between any two MEPs in the present application may be carried in a message.

Specifically, the type of the message may be an Identity Check (IC) type, or other names, which is not limited in this application. The value of its operation type (OpCode) can be set to 60 to avoid duplication with the value of the preamble operation type.
