【 摘 要 】

The VPN technology is used to connect client devices securely over unsecured public networks. The Connection handover and Dead Peer Detection (DPD) are the most challenging and important tasks in VPN. In this present article, a solution for connection handover is proposed which covers the pre-authentication with new credentials for a mobile device prior to connection handover. In VPN, a case where such connection handover is failed due to incomplete connection handover or several unusual events which make a VPN client to become offline or dead. To address DPD issues a solution is proposed which includes a Keep Alive Timer (KAT) server at the VPN server side. This proposed solution for DPD is far better than an already existing solution that uses a DNS server for DPD since the DNS server faces several attacks consistently. Thus, the proposed solution for DPD is more secure against such vulnerable attacks.
