Optimized cryptographic binding protocol using MIPv6 over IEEE 802.16e

In the mobile telecommunication network, the expansion in Internet traffic will cause the demand for IP addresses. Further WiBro will also stimulate the interworking for IP addresses. In fact, many working groups are designing an adaptation mechanism between WiBro and IPv6/MIPv6. Accordingly, from the viewpoint of security, interworking between 802.16e and MIPv6 is essential. In this paper, we propose a secure and efficient OCBP(Optimized Cryptographic Binding Protocol) between Layer 2 and Layer 3 of WiBro system.
