“…To improve security, the authentication schema involves integrating encryption techniques, such as ''RSA-based public key cryptosystem'' [60], ''Secure Hash Agorithm (SHA)'' [61], ''Advanced Encryption Standard (AES)'' [62], and ''Elliptic Curve Cryptography (ECC)'' [63]. In recent years, ''access control, authentication and key management'' are widely-used two main security mechanisms in providing security in IoT-enabled environments [64], [65], [66], [67], [68], [69], [70], [71], [72], [73], [74], [75], [76], [77], [78], [79], [80].…”
