摘要
Due to the resource-constrained of Internet of things(IoT)devices,the traditional cryptography protocols are not suitable for IoT environments.When they can be implemented,their performances often are not acceptable.As a result,a lightweight protocol is required to cope with these challenges.To address security challenges in IoT networks,we present a lightweight mutual authentication protocol for IoT.The protocol aims to provide a secure mutual authentication mechanisms between the sensor node and gateway using a lightweight cryptography algorithms.The protocol is relied on two main shared secret keys,a permanent key(kp)used for encrypting messages during the mutual authentication phase and an update key(ku)used for the communication session.The session key is constantly updated after a pre-defined session time(sesstimei)by using the previous session information.We used a lightweight cryptography mechanisms that includes symmetric-key cryptography,hash-based message authentication code(HMAC),and hash function to design the protocol.We analyze the protocol using the Barrows-Abadi-Needham(BAN)-logic method and the results show that the proposed scheme has good security and performance compared to existing related protocols.It can provide a secure mutual authentication mechanism in the IoT environment.
