CMAKM-FIoT: centralised mutual authentication and key management scheme for fog computing-enabled IoT network

Abstract

Nowadays, fog computing plays an indispensable role in delay-sensitive internet of things (IoT) applications. However, openness and lack of human intervention make fog computing-enabled IoT (F-IoT) network vulnerable to various cryptographic attacks. Therefore, reliable mutual authentication and a key agreement scheme are essential. Many authentication schemes have been proposed for the F-IoT network. However, they are not appropriate for resource-constrained networks due to high communication and computation overhead. In this paper, centralised mutual authentication and key management scheme called CMAKM-FIoT is designed and proposed. The security analysis of proposed scheme indicates that it is robust against various cryptographic attacks. The performance evaluation has evaluated and compared with existing related schemes in terms of computation and communication overhead. The proposed scheme achieves better security than previous related schemes, according to the performance evaluation and security analysis.
