A Survey of Security Vulnerability Analysis, Discovery, Detection, and Mitigation on IoT Devices With the prosperity of the Internet of Things (IoT) industry environment, the variety and quantity of IoT devices have grown rapidly. IoT devices have been widely used in smart homes, smart wear, smart manufacturing, smart cars, smart medical care, and many other liferelated fields. With it, security vulnerabilities of IoT devices are emerging endlessly. The proliferation of security vulnerabilities will bring severe risks to usersxe2x80x99 privacy and property. This paper first describes the research background, including IoT architecture, device components, and attack surfaces. We review stateoftheart research on IoT device vulnerability discovery, detection, mitigation, and other related works. Then, we point out the current challenges and opportunities by evaluation. Finally, we forecast and discuss the research directions on vulnerability analysis techniques of IoT devices.

A Comprehensive Survey of Prominent Cryptographic Aspects for Securing Communication in PostQuantum IoT Networks Abstract   Internet of Things (IoT) ideates smart and interconnected things capable of sharing their perceptions through the Internet. These devices are different from conventional Internetconnected devices in the sense that these are able to perform skillfull things on their own with minimal or no human interaction. Unfortunately, with the advent of amalgamate technologies, security has become a major concern for IoT networks. Recent efforts include reinventing cryptographic solutions through the use of lightweight operations. However, after witnessing the growth of quantum computers, it can be inferred that the cryptographic techniques based on mathematical problems are not reliable enough. Therefore, there is need to develop solutions that can easily resist the adversarial effects and are suitable for the postquantum world. In this paper, we perform indepth analysis over the role of postquantum cryptographic techniques for securing IoT networks and also explore ongoing research efforts in the field. In addition, we discuss the open research challenges and future research directions in the field.
