Light Weight Authentication Scheme for Smart Home IoT Devices

In today’s world, the use of computer networks is everywhere, and to access home network we Internet. IoT are new range these in which try connect different appliances give commands from a remote place. Access any device over an insecure invites various types attacks. User authentication can be performed using some password or biometric technique. However, when it comes authenticating device, becomes challenging maintain data security secure such as Many encryptions decryption algorithms assert confidentiality, hash code message MAC used for authentication. Traditional cryptographic methods expensive terms computational resources memory, processing capacity, power consumption. They incompatible with Internet Things devices that have limited resources. Although automatic Device-to-Device communication enables potential applications, networks’ machines impose constraints. This paper proposes scheme accessed An controller control appliances. Our prevent attacks replay attacks, server spoofing, man-in-the-middle attack. The proposed maintains confidentiality authenticity user network. At same time, check system simulated environment, results show network’s performance does not degrade much delay, throughput, energy consumed.
