概要 |
The Internet of Things (IoT) is a network of various interconnected devices that communicate and exchange data through the Internet. The IoT devices rely on the unreliable web for data transfer; there...fore, it is vital to develop secure communication to safeguard end-to-end communication among these devices. IoT devices must transmit data that is resistant to a variety of hostile attacks to reduce energy consumption while maintaining data privacy and integrity. The existing Public Key Infrastructure (PKI)-based secure authentication technique is challenging in many IoT devices due to associated costs with key distribution and management. Therefore, we provided a novel identity authentication system for energy-efficient IoT devices. This paper proposes an Energy-efficient and Secure Identity Authentication (ESIA) scheme for the delay constraint, low power and secure communication in IoT networks. The proposed method achieves mutual identity authentication between IoT servers and devices using three steps: initialization, pairing, and authentication. These steps establish secure sessions among the interacting devices. The proposed scheme enhances the security of IoT devices by removing the need for third-party authentication. The ESIA scheme is robust, energy efficient and resistant to a variety of possible attacks. The simulation results show that the proposed method transmits data with less computation and transmission overhead than existing methods.続きを見る
