Embodiment Construction

[0023] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0024] figure 1 It is a flow chart of the inventive method, comprising the following steps:

[0025] A. The sender initiates a negotiation message;

[0026] B. If there is an exception, the receiving end will respond to the sending end with an abnormal information message, and mark the receiving end as inactive within the first set time;

[0027] C. After receiving the abnormal information message, the sending end marks the sending end as inactive within a second set time.

[0028] Wherein, the negotiation message in the step A carries configuration information, and the configuration information includes an encryption key and a negotiation policy.

[0029] Further, the...

Abstract

The invention discloses a method for processing abnormalities in IKE negotiation, which specifically includes: a sending end initiates a negotiation message; if an abnormality occurs, the receiving end responds with an abnormal information message of the sending end, and marks the receiving end within a first set time is in an inactive state; after receiving the above-mentioned abnormal information message, the sending end marks the sending end as an inactive state within a second set time. When the IKE negotiation is abnormal, this method can prevent the continuous sending of negotiation packets, avoiding excessive occupation of network resources and system memory resources.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a method for processing abnormalities in IKE negotiation. Background technique [0002] Internet Protocol Security (IPSec) is an end-to-end mechanism designed by IETF (InternetEngineeringTaskForce) to ensure the security of Internet IP layer communication, including Network Authentication Protocol (AH), Encapsulating Security Payload Protocol (ESP), Key Exchange Protocol (IKE ) and some algorithms for network authentication and encryption, etc. [0003] Among them, the process of Internet Key Exchange (IKE) is divided into two parts: the first phase negotiation and the second phase negotiation. During the negotiation, the devices at both ends of the network need to exchange messages. These messages are used to exchange and confirm configuration, Authentication, key information, etc. In the actual exchange process, when the configuration information of the devices at both ...
