Abstract

Internet of Things (IoT) is an advanced applied science in recent years that enables communication among humans and smart components or among Internet-based components. Besides, IoT provides affiliation of physical and virtual elements that are fully controlled by different kinds of hardware, software, and interaction advancements. Though numerous methods of IoT offer many advantages to our day-to-day routine, it also possesses huge security weaknesses. The traditional methods are vulnerable to a huge range of attacks. Hence, establishing safe and effective security alternatives for the IoT environment remains as a main challenge and the major risk in this security solution is to transfer significant information in a secure manner. To address such limitations, an effective authentication approach named CHEK-based authentication methodology is devised for secure communication in IoT. The proposed authentication scheme consists of four steps and the authentication approach is developed by considering various security operations like hashing, encryption, secret key pairs, passwords, and so on. Moreover, the CHEK-based authentication scheme provides promising solution with minimum computational cost of 16.541 and minimum memory usage of 72.3MB.
