Security over internet communication has now become difficult as technology is increasingly more effective and faster, particularly in resource limited devices such as wireless sensors, embedded devices, internet of things (IoT), radio frequency identification (RFID) tags, etc. However, IoT is expected to connect billions of computers as a hopeful technology for the future. Hence, security, privacy, and authentication services must protect the communication in IoT. There are several recent considerations, such as restricted computing capacity, register width, RAM size, specific operating environment, ROM size, etc. that have compelled IoT to utilize conventional measures of security. These technologies require greater data speeds, high throughput, expanded power, lower bandwidth, and high efficiency. In addition, IoT has transformed the world in light of these new ideas by offering smooth communication between heterogeneous networks (HetNets).
