A network-assisted mobile VPN for securing users data in UMTS

This paper proposes a network-assisted mobile Virtual Private Network (mVPN) security scheme that provides secure remote access to corporate resources over the Universal Mobile Telecommunication System (UMTS). The proposed scheme, which is based on IPsec, distributes the required security functionality for deploying a VPN between the involved user's device and the mobile network limiting the configuration, computation and communication overheads associated with the user and its device. The network-assisted mVPN addresses the security weaknesses of the UMTS technology in protecting users' data and satisfies the security requirements of the mobile users. It can be integrated into the UMTS network infrastructure requiring only some limited enhancements to the existing mobile network architecture, and without disrupting the network operation. For the initialization of a network-assisted mVPN and the related key agreement an extension of Internet Key Exchange version 2 (IKEv2) is...
