Optimal Design of IPsec-Based Mobile Virtual Private Networks for Secure Transfer of Multimedia Data

Abstract

Optimal design of IPsec-based mobile virtual private networks (MVPN) for a secure transfer of multimedia data, in general case, depends on multiple factors and parameters such as to-be-selected MVPN’s architectural model, hardware and software setups and technical platform’s solutions, network topology models, modes of tunnel’s operation, levels of the Open Systems Interconnection (OSI) model, encryption/decryption algorithms, modes of cipher operation, security protocols, security associations and key management techniques, connectivity modes, parameters of security algorithms, computer architectures, number of tunnels in MVPN, and other factors. This paper presents the outcomes of research project on multi-objective optimization of IPsec mobile virtual private network design based on non-isomorphic groups of order 4—Cayley Tables—for three major MVPN factors: (1) level of data transfer security provided by MVPN, (2) MVPN performance and (3) cost of designed virtual private network.
