Location Privacy in Mobile IP

Abstract

Several security issues arise, due to the design of the Mobile IP and its deployment in conjunction with other network protocols. Most of the work on the security of Mobile IP has focused on authentication of the control packet and the confidentiality of the content in the protocol, and there are not many proposals in the area of location privacy. In this paper, we propose a method to provide location privacy for Mobile IP users. We present two protocols that use an overlay network approach, and designed particularly for Mobile IP. We employ universal re-encryption and extend it to n-out-of-n universal reencryption to achieve our goal. In contrast to other overlay network approaches, where at least n public key encryption are required, our scheme requires only 2 public key encryption operations. Therefore, it is applicable to Mobile IP systems, where in most cases the mobile nodes are small devices and have computational limitation.

Lattice Based Mix Network for Location Privacy in Mobile System

“…This information can be used for blackmail by malicious user. Wiangsripanawan et al [11] proposed a protocol for location privacy in mobile system using universal reencryption [4] whose security is reducible to Decision Diffie-Hellman assumption. Once quantum computer becomes a reality, universal reencryption can be broken in polynomial time by Shor's algorithm [5].…”

“…In post quantum cryptography, our scheme can replace universal reencryption scheme used in Wiangsripanawan et al [11] protocol for location privacy in mobile system.…”

ALPP: anonymous and location privacy preserving scheme for mobile IPv6 heterogeneous networks

“…Therefore, revealing an MN's HoA means breaking its anonymity, and revealing an MN's CoA means breaking its location privacy. On one hand, some existing anonymity and location privacy schemes require intensive computations; hence, they cannot be used in the timely restricted seamless handover processes. On the other hand, some other schemes achieve low anonymity and location privacy levels.…”
