An Efficient NTRU-Based Authentication Protocol in IoT Environment

Recently, to ensure privacy of user, the numerous elliptic curve cryptosystem based key distribution and authentication protocols for IoT environments have been proposed. However, most used public key based cryptosystems such as ECC and RSA cannot resist quantum computing attacks. In this paper, to overcome this security issue, we propose a NTRU based authentication and key distribution protocol. Our proposed protocol has also high performance compared with ECC based key distribution protocol. Therefore, the proposed protocol can be applied to practical field such as smarthome, smartgrid and healthcare efficiently.
