A Provable Secure Cybersecurity Mechanism Based on Combination of Lightweight Cryptography and Authentication for Internet of Things

Internet of Things devices, platform programs, and network applications are all vulnerable to cyberattacks (digital attacks), which can be prevented at different levels by using cybersecurity protocol. In the (IoT), specifically intended retrieve or change/destroy sensitive information that may exceed IoT’s advantages. Furthermore, design a lightweight mechanism experiences critical challenge would perfectly fit resource-constrained IoT devices. For instance, identifying compromised devices users’ data services protection general challenges on an system should considered. This paper proposes secure based integration cryptography with authentication (ELCA) utilizes elliptic curve Diffie–Hellman (ECDH) undertake key distribution while weak bits problem in shared secret is resolved. this paper, three systems investigated, ELCA between encryption facilitate confidentiality authenticity transfer messages over insecure communication channel. security proven mathematically random oracle model adversary model. The findings emulation results show effectiveness performance terms reduced CPU execution time 50%, storage cost 32–19.6%, energy consumption 41% compared baseline cryptographic algorithms.
