A proposed protocol for Internet key exchange (IKE)

Internet key exchange (IKE) manages keys securely after they have been agreed upon and IKE exchanges the keys in an authenticated way. IKE has some deficiencies, the three most important of which are the excessive number of messages, IKE´s vulnerability. to denial of service (DoS) and the complexity of IKE´s specification. To solve these problems, some successors have been presented for IKE such as IKEv2, SIGMA and JFK. We have also tried to introduce a suitable successor for IKE in the extended version of this paper. The proposed protocol has all the functionalities of other successor protocols; however, the number of messages in this protocol are less than other protocols and the method for the prevention of DoS attack in this protocol is better than the other methods.
