The invention discloses a method and equipment for negotiating an internet key exchange (IKE) message and is applicable to a system which adopts an internet protocol security (IPSec) protocol and comprises first equipment and second equipment. The method comprises first-stage negotiation and second-stage negotiation. During the second-stage negotiation, the first equipment sends the last negotiation message to the second equipment and then judges whether a response message which is sent by the second equipment is received in a preset period; if the first equipment does not receive the response message which is sent by the second equipment in the preset period, after receiving an encapsulating security payload (ESP) message and an authentication header (AH) message, the first equipment searches corresponding IPSec security association (SA) in a security association database; if the IPSec SA waits for the last response message of the second-stage negotiation, the first equipment continuously performs decryption by using the IPSec SA; if decryption succeeds, the state of the IPSec SA is marked as 'active'; and establishment of the IPSec SA of the first equipment is finished, and the response message of the second equipment is ignored. By the invention, the problem of IPSec tunnel oscillation or network disconnection caused by network congestion and message loss is solved.
