With the advent of 5G networks in the era of Internet of Things (IoT), wireless and mobile networking have become prevalent everywhere. In this scenario, security and privacy have become the decisive factors. Mobile and wireless ecosystem is an ideal playground for countless perpetrators. (i) Handheld devices are often utilized for critical tasks, such as e-commerce, bank transactions, and application purchases as well as social interactions. (ii) These devices uniquely identify their users and store sensitive and meticulous information about them. (iii) Despite their sophistication, naive security mechanisms have culminated in the bypassing of the mobile operating systems. Moreover, several wireless interfaces and protocols have been found to be vulnerable. As the attacker has a multitude of alternate entry points to perform penetration, the inception of assaults against the user and underlying systems have augmented both in amount and in matters of complexity. It is, therefore, imperative that novel and advanced security and privacy preserving measures be deployed.
