The invention proposes a two-way authentication network management protocol method and system. Step S1, two-way authentication for device access; step S2, two-way authentication for control operations: the device network management sends configuration data to the managed device, enables / closes ports, and terminal messages are encrypted and transmitted using the key negotiated in step S1 ; Step S3, two-way authentication of test operation: the device network management sends a test command to the managed device or the message of the test result returned by the managed device to the network management system, and uses the negotiated key in step S1 to carry out encrypted transmission; step S4 2. Two-way authentication of query operation: the device network management obtains the message of status, configuration, and performance data from the managed device, and uses the key negotiated in step S1 to encrypt and transmit; step S5, two-way authentication of the main report operation: the managed device actively sends The event or message message reported by the device network management is encrypted and transmitted using the key negotiated in step S1.
Description
technical field [0001] The invention belongs to the field of communication network protocols, in particular to a network management protocol method and system for two-way authentication. Background technique [0002] The most important part of the network management system is the network management protocol, which defines the communication method between the network manager and the network agent, and is the basis for maintaining the normal operation of the network. In recent years, with the rapid development of computer technology and network, network management has been paid more and more attention by people. Generally speaking, network management includes the use, synthesis and coordination of hardware, software and manpower, through which network resources are monitored, tested, configured, analyzed, evaluated and controlled, which is conducive to meeting some network needs at a reasonable price , such as real-time performance, quality of service, etc. Its purpose is to...
