5. Conclusion
In EAP-AKA protocol, the fast re-authent ication has the
better authentication performance ... inefficient authentication/ re -authentication protocol also causes long authentication/ re-
authentication latency. Therefore, this article proposes a novel protocol named fast iterative localized re-
