Security Challenges and Issues in IoT

Internet of Things (IoT) is sometimes called the internet of devices. In IoT, environment devices are connected with the help of gateways. All required information can be accessed by a device with the help of internet gateways from any network. So, it is very challenging to transfer data in open surroundings where the security of data is very problematic. In this paper architecture of IoT, security challenges, security requirements, and future security challenges of IoT have been discussed in detail, after that, a comparative analysis of different security techniques has been presented. At last literature review on different papers of security in IoT has been presented with pros and cons.
