Abstract: Future Internet (FI) will be shaped by the Internet of Things (IoT), however because of their limited resources and varied communication capabilities, IoT devices present substantial challenges when it comes to securing connectivity. The adoption of robust security measures is hindered by limited compute power, memory, and energy resources, hence diminishing the promise for improved IoT capabilities. Confidentiality, integrity, and authenticity are ensured via authentication mechanisms are influenced by privacy needs, which are driven by sorts of customers that IoT networks service. Authentication is crucial in vital industries like linked cars and smart cities where hackers might use holes to access sensor data. Verification of the Gate Way Node (GWN), which is responsible for mutual authentication, user and sensor registration, and session key creation, is essential. The efficiency of key creation has been enhanced to tackle temporal intricacies linked to different key lengths. With notable advantages, the novel method shortens the time required to generate cryptographic keys: only 60 milliseconds for 100-bit keys and 120 milliseconds for 256-bit keys. This improvement fortifies resistance against new cyber threats by strengthening security basis of IoT networks and enhancing responsiveness and dependability. Through open transmission channels, users send login requests, and after successfully authenticating, they create session keys to establish secure connections with cloud servers. Python simulation results show how resilient the system is to security threats while preserving affordable interaction, processing, and storage. This development not only strengthens IoT networks but also guarantees their sustainability in the face of changing security threats.
