SIDP: A Secure Inter-Domain Distributed PMIPv6

Proxy Mobile IPv6 (PMIPv6) offers centralized
network-based mobility support for mobile nodes (MN). This
centralized nature of mobility leads to the performance issues
such as single-point failure, non-optimal routing, low scalability,
authentication latency, and signaling overhead. Additionally,
PMIPv6 does not support inter-domain handover due to which
the on-going sessions cannot be maintained between two
PMIPv6 domains. The existing solutions for inter-domain
mobility management are considered to be unsuccessful to cope
with this problem. In this paper, a novel approach called Secure
Inter-domain Distributed PMIPv6 (SIDP) is proposed to
overcome the aforementioned issues. The SIDP separates
traditional mobility anchors into Control Mobility Anchor
(CMA) and Data Mobility Anchor (DMA). CMA holds the
functionalities of Mobile Access Gateway (MAG) and control
plane whereas DMA buffers and forwards the data plane
packets. We present basic design, DMA decision process, strong
authentication, dynamic mobility management, optimized
routing, and inter-domain handover of our proposed scheme.
The authentication procedure is based on symmetric
cryptographic and collision free one-way hash function to make
the distributed mobility management secure. The security
analysis demonstrates that the proposed scheme possesses user
anonymity, fraud avoidance, mutual authentication, forward
secrecy, backward secrecy, and one-time session key agreement.
