In this 21st century IoT is one of the exploding technologies in the consumer and business environments. As more and more devices are getting connected to the network, the urge of device authentication is growing high due to the requirement of secure communication with each other as well as the backend infrastructure. For its value to be realized any IoT device should first respect the confidentiality between the users. In this paper, we have proposed a authentication approach that works in two levels to provide a high level of security and surety for the data transmitted. We have presented asymmetric encryption for the data using public and private keys. Further, the unique MAC addresses of connected IoT devices has been exploited and encrypted using Triple DES method which acts as a second layer lock to increase the confidentiality of data.
