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 processing method for the abnormality of IKE (internet key exchange) negotiation. The processing method specifically comprises the following steps of: transmitting a negotiation message by a transmitting end; in case of abnormality, responding an abnormal information message of the transmitting end by a receiving end, and marking the receiving end as a non-activated status within a first set time; and marking the transmitting end as the non-activated status within a second set time after the transmitting end receives the abnormal information message. When the IKE (internet key exchange) negotiation is abnormal, the method can prevent the negotiation message from being continuously transmitted, so that the excessive occupancy of network resource and system memory resource can be avoided.

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 (Internet Engineering Task Force) to ensure the security of Internet IP layer communication, including Network Authentication Protocol (AH), Encapsulation 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 bot...
