A protocol optimization framework and method for network management protocol snmpv3

Abstract

The invention discloses a protocol optimization framework and method for the network management protocol SNMPv3, which belongs to the technical field of network security protocols, and solves the problem that in the prior art, the handshake based on the existence of SNMPv3 does not support key negotiation and certificate authentication, resulting in protocol deployment It is extremely inconvenient and has poor adaptability. In addition, the handshake of the SNMPv3 protocol does not provide data integrity and confidentiality services. The handshake message is transmitted in plain text, and there is a risk of key parameter leakage. The present invention includes: protocol encryption module: used for data encryption of protocol messages in communication and handshake; protocol authentication module: responsible for data authentication of protocol messages in communication and handshake; protocol handshake module: based on protocol encryption module and The protocol authentication module performs security handshake; the protocol communication module: based on the protocol encryption module, the protocol authentication module and the protocol handshake module, the communication message transmission is carried out. The invention is used for protocol optimization.

Description

technical field [0001] A protocol optimization framework and method for network management protocol SNMPv3 are used for protocol optimization and belong to the technical field of network security protocols. Background technique [0002] Today's era is the era of information technology.
