| Abstract: | This paper analyzes the negotiations of IKE SA based on pre shared key, demonstrates a security flaw on the authentication of IKE SA, and defines a new method for calculating the authentication HASH of the IKE SA protocol. The new method makes the memory consumption smaller and improves the security of the IKE SA. |
