Security Challenges: M2M Communication in IoT

In recent times, smart devices, homes, manufacturing, and even cities, all of which are connected to the Internet Things (IoT) have become quite common. IoT technology heavily relies on Machine-to-Machine (M2M) communication in order make technologies behave a way. Any type connection between two devices that does not require human intervention is referred as "machine-to-machine" technology. The system with unique identifiers can transmit information over network. There no interaction humans or machines IoT. now widely used variety sectors, including banking (connected branches), industries where secrecy privacy data important components. allows multiple design network, whereas M2M makes it possible for communicate one another. Therefore, this paper gives brief review work security challenges faced significance both technologies.
