The "Internet of Things" (IoT) is an emerging technology that allows electronic devices and sensors to connect over the Internet. The IoT is a network of smart devices, such as sensors, that are connected through cables or wirelessly. Today, IoT devices are commonly used in medical science, industrial automation, and smart home automation, among other applications. Easy accessibility and the open-source environment of IoT devices are major threats to privacy and security. In this research,we briefly discuss areas of IoT, including architecture and details of IoT layers concerning security algorithms, protocols, attacks, and their mitigation. The primary purpose of this research is to provide an efficient and cryptographically proven algorithm scheme with appropriate hardware to improve IoT device network security. This research enhances the network security of IoT devices by presenting a key agreement protocol (ECDSA) with data integrity and a unique key in every session instead of afixed key or password for authentication of devices with centrally controlled device/server (CCD/S) and data encryption supported by the finest hardware options. After evaluating several cryptographic algorithms and hardware options, the proposed solution is more secure by using separate key pairs for authentication and a unique shared secret for each message between IoT devices and CCD/S. This research is an important step towards ensuring the integrity and security of IoT devices in a networkedenvironment, with the primary goal of increasing the protection of sensitive data and interactions.
