Hybrid and Adaptive Cryptographic-based secure authentication approach in IoT based applications using hybrid encryption

Abstract

The Internet of Things (IoT) in communication networks has gained major interest in recent decades. Accordingly, secure authentication of such individuals results in a major challenge due to the weakness in the authentication process. Hence, an effective Hybrid and Adaptive Cryptographic (HAC)-based secure authentication framework is designed in this research to perform an authentication process in IoT. The proposed approach uses cryptographic operations, like exclusive-or (Ex-or) operation, a hashing function, and hybrid encryption to accomplish the authentication process. However, the hybrid encryption function is carried out in two different ways: one depends on Advanced Encryption Standard (AES) as well as Elliptic Curve Cryptography (ECC), while other is based on Rivest Shamir Adleman (RSA) and AES. With a hybrid encryption function, security flaws can be effectively dealt through the cryptographic system. Moreover, the proposed approach provides high robustness with low complexity. The proposed HAC-based secure authentication approach obtained a minimum communication cost of 0.017sec, less computation time of 0.060sec, and minimum memory usage of 2.502MB, respectively.
