The concept of Internet of Things (IoT) is continuously evolving day to day and thus allowing various applications in different fields such as agriculture, education, industry, health, transportation etc. IoT being applied over these areas is influencing in a direct manner our lives, standing behind concepts like smart city, smart payment transfer, smart transportation, smart grid etc. In the IoT model, Internet-connected embedded devices perform manipulation on different sensitive data of users and need enough security solutions. The security solutions designed for network-enabled embedded devices must resolve issues like availability and usability, taking into account that IoT appliances require low computational capabilities and low consumption. It is difficult to implement IoT security solutions due to the factor that the newly purchased IoT devices are not equipped with a digital identity; therefore a user-friendly mechanism must handle the security material provisioning and attach the IoT device to the user cloud component account. This paper provides an in-depth literature review on IoT security issues and presented a modified hashing algorithm that is more efficient in device communication.
