Abstract
A security enhancement to IPSec processing is achieved by changing the algorithms used at each re-key after expiration or termination of a Security Association session between two peer nodes. The solution enables an Internet Key Exchange to negotiate multiple algorithms to ensure that every renewed IPSec Security Association has a different algorithm combination, thereby making attempts at decryption by an attacker more difficult.
