Abstract

In this manuscript, we analyze the security offered by existing 802.11 protocols against one of the most basic yet detrimental Evil Twin (ET) attacks. To comprehensively protect Wi-Fi networks against such attacks, vulnerabilities in the IEEE 802.11 specifications were addressed by new and improved security mechanisms. Unfortunately, each of the existing 80 2.11 protocols resulted in a significant increase in communication and computation overhead, making them unsuitable for low latency applications such as health care, intelligent transportation systems, robotics, Industrial Internet of things (IIoT), etc. A protocol is needed which provides optimum security against contemporary network attacks while keeping the latency and overhead maintained. In this work, we propose a secure and low latency protocol known as SAP, which incurs low computation overhead, exchanges less number of messages, does not require any pre shared knowledge, and yet provides end to end security to messages exchanged, making it ideal for embedded and IIoT applications. The protocol is validated using formal verification techniques and experimental simulation.
