Abstract
The Internet of Things enables communication between diverse devices from different vendors via a common platform that provides the necessary support in making the communication possible. These are generally unsupervised networks that are liable to threats arising from different kinds of external attacks. Hence, the security of devices, communication, and data becomes a priority issue in this kind of setup. One of the preliminary measures considered to combat these threats is Authentication, which acts as a preventive approach. It aids in detecting the legitimacy of the communicating parties, whether humans or other interconnected smart devices. Another approach to enhance security is the use of Virtual Private Network, which is slowly replacing the wired networks. The data transmitted in these wireless networks often remains more secure and reliable. This chapter discusses the VPN methodology, presents the relevant analysis and the outcomes. The proposed study utilizes the Virtual Private Network infrastructure setup and adopts Mutual authentication protocols, using the Global Positioning System, before proceeding with the actual data transmission. We establish that authentication using Global Positioning System considerably enhances the overall security of the network. Furthermore, considering that energy is a scarce resource, we discuss the preservation of the same. The work we present reduces energy consumption by 82% compared to the previous similar studies. In our proposal, the authentication keys generated are different for every session. This measure also tackles Wormhole attacks in the network. It ensures a 4% increase in security in comparison to previously published work. The proposed work also preserves forward-secrecy.
