Enhancing IoT Security with Multilayer Authentication and End-to-End Encryption

The internet of things is a sophisticated network of all the items that are controllable online. Owing to its advanced accessibility and management qualities, it is seen as one of the most sought-after pieces of technology in the upcoming periods. Its ability to support a wide range of things in daily life has demonstrated its effectiveness in serving human society. It must contend with security issues including peer-to-peer authentication and data secrecy from prying eyes. Due to the multicast user approach of the Internet of Things, there is constant contact between the user and the many objects. To protect our resources from any kind of security breach or vulnerability, a robust security system is needed. Thus, focusing on this specific issue, we suggested a method that combines two security techniques. The first is the Elgamal end-to-end security mechanism, which is followed by a tiered authentication strategy. This technique operates in two stages: in the first, the sub-server and the authentication procedure work together to provide authentication for access to the main data server, and in the second. When a user gets close to the actual server, he must use the public cryptography technique, which encrypts data using Elgamal cryptography to offer end-to-end security. Every aspect of the task is thoroughly examined using the cryptography and authentication factors at hand. Ultimately, the suggested solution will offer robust security to better facilitate communication and preserve data.
