Information security of mobile VPN: Conceptual models and design methodology

Virtual Private Network (VPN) is one of the most reliable technologies to provide data protection, confidentiality, integrity, data origin authentication, replay protection and access control [1]. An exponential growth of mobile computing, mobile networks, and mobile applications demand utilization of highly effective algorithms, models and sets of technical specifications of mobile virtual private network (MVPN) in terms of security, performance and cost. This paper presents the outcomes of 5-year long research, design, development and implementation activities aimed at engineering of practical MVPN solutions for various types of network users. It describes conceptual models and design methodology of information security of MVPN solutions, and provides network managers and/or system administrators with recommendations on engineering of specific IPsec MVPN solutions for various types of network users.
