Abstract

With the help of various Layer 2 triggers, Fast Handover for Mobile IPv6 (FMIPv6) considerably reduces the latency and the signaling messages incurred by the handover. Obviously, if not secured, the protocol is exposed to various security threats and attacks. In order to protect FMIPv6, several security protocols have been proposed. To our best knowledge, there is lack of analysis and comparison study on them though the security in FMIPv6 is recognized to be important. Motivated by this, we provide an overview of the security protocols for FMIPv6, followed by the comparison analysis on them. Also, the security threats and requirements are outlined before the protocols are explored. The comparison analysis result shows that the protocol presented by You, Sakurai and Hori is more secure than others while not resulting in high computation overhead. Finally, we introduce Proxy MIPv6 and its fast handover enhancements, then emphasizing the need for a proper security mechanism for them as a future work.

고속의 이동 IPv6 (FMIPv6: Fast Handover for Mobile IPv6) 프로토콜은 2 계층에서 지원 가능한 트리거의 도움으로 핸드오버시 발생하는 과도한 지연시간과 시그날링 메시지를 효과적으로 감소시켰다. 뛰어난 효율성에도 불구하고 FMIPv6는 다양한 공격과 위협에 노출되어 있기 때문에 이를 보호하기 위한 여러 보안 프로토콜이 제안되었다. 본 논문에서는 FMIPv6의 취약점 및 보안요구사항을 정의한 후, 이를 바탕으로 주요 보안 프로토콜의 보안특성을 비교 분석하였다. 분석결과는 본 저자들에 의해 제안되었던 프로토콜이 다른 기법에 비해 과도한 연산을 유발하지 않으며 강력한 보안성을 지니고 있다는 것을 보여 주었다.
