AI Technical Summary

Technical Problem

It is difficult for the prior art to quickly locate the problem of encryption data communication caused by network reasons or the problem of encryption after negotiation is completed. Especially in abnormal situations caused by intermediate network equipment policies such as firewalls, routers, and encryption machines, manpower is needed to analyze and investigate, resulting in the problem being unable to be quickly locate.

Method used

By generating a service detection request based on the key negotiation diagnostic instruction issued by the management end on the service requesting party, and sending it to the service responding party, obtaining a network response message, and determining its message format is consistent with the message format of the preset key negotiation diagnostic protocol. If it is consistent, the diagnostic protocol analysis is carried out, the service detection result is determined and sent to the management end so that the management end can determine the abnormal situation of the key negotiation.

Benefits of technology

A method of quickly determining the cause of abnormalities in the key negotiation process is realized, which reduces the time for manpower analysis and investigation, and improves the efficiency of key negotiation abnormal diagnosis.

Abstract

The invention discloses a key negotiation abnormity diagnosis method and device, equipment and a storage medium, relates to the field of network security, is applied to a service requester, and comprises the following steps: generating a service detection request for a service responder based on a key negotiation diagnosis instruction issued by a management end, and sending the service detection request to the service responder; obtaining a network response message sent by a service responder for the service detection request, and judging whether the message format of the network response message is consistent with the message format of a preset key negotiation diagnosis protocol; if the message format of the network response message is consistent with the message format of the preset key negotiation diagnosis protocol, performing diagnosis protocol analysis on the network response message to obtain a corresponding protocol analysis result; and determining a service detection result based on the protocol analysis result, and sending the service detection result to the management end, so that the management end determines a key negotiation abnormal condition based on the service detection result. According to the invention, the key negotiation abnormity can be diagnosed.
