Problems solved by technology

[0008] However, the Y.1731 protocol itself does not consider security
And in real carrier networks, protocols that lack security can easily become targets of network attacks

Embodiment Construction

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the present invention.

[0032] like figure 1 As shown, the method for setting OAM security authentication proposed by the present invention pre-defines a key for the network devices at both ends of the ME, and the key will not be transmitted in the network, but stored inside the device. Set an identity authentication TLV (Type Length Value) field in the OAM message sent by the network device at the ME end. The identity authentication TLV field includes an MD5 (Message-Digest Algorithm 5, information digest algorithm fifth edition ) value and sequenceID, the MD5 value is the MD5 value of the sender, which is the result of the "logical AND" operation between the sequenceID and the key in the OAM message.

[0033] When the network device at the other end of the ME receives the OAM message, it performs a "logic...

Abstract

The invention provides a method and a device for setting operation, administration and maintenance (OAM) security authentication. The method comprises the following steps of: pre-setting keys on network equipment at two ends of a maintenance entity, and when the network equipment at one end sends an OAM message, adding an identity checking threshold limit value (TLV) field into the sent OAM message, wherein the field comprises a sending end MD5 value, and the sending end MD5 value consists of a sequenceID field and key logic operation; when the network equipment at the other end of the ME, performing corresponding logic operation on the sequenceID field in the message and a locally preset key to obtain a receiving end MD5 value; and comparing the two MD5 values, and if the two MD5 values are the same, determining that the OAM message passes through the authentication, otherwise, abandoning the message. Therefore, the OAM communication security is guaranteed, and equipment for running a continuity fault management (CFM) protocol difficultly suffers from hostile attack of the Internet.

Description

technical field [0001] The invention relates to the technical field of computer communication, in particular to a method and a device for setting OAM security authentication in the CFM protocol of the computer network communication technology. Background technique [0002] According to the actual needs of the operator's network operation, the network management work is usually divided into three categories: operation (Operation), management (Administration), maintenance (Maintenance), referred to as OAM (Operation Administration and Maintenance). Operation mainly completes the analysis, prediction, planning and configuration of the daily network and services; maintenance mainly refers to the daily operation activities such as testing and fault management of the network and its services. [0003] CFM (Continuity Fault Management, connection fault management) based on Y.1731 has been widely used in carrier networks. According to the functional distinction of CFM, it can be di...
