In Fourth generation wireless network (4g) , increasing demand of wireless networks, to provide seamless and secure handoff has become an important factor in wireless networks. To monitor unauthorized access, modification, misuse and network-accessible resources various provisions and policies are adopted by the network in network security process. In a wireless environment, data is broadcast through the air and people do not have physical controls over the boundaries of transmissions. Some wireless products have weaker security features so to attain the higher levels of integrity, authenticity, and confidentiality, network security features need to be embedded in the handoff policies. In order to provide continuous service we proposed in a Distributed Vertical Handover Decision (DVHD) scheme, we will present a Secured Vertical Handoff Decision (Sec-DVHD) scheme using PKM(Public Key Management.
