The pervasive nature of computing makes classical solutions inapplicable for handling communication between peers in the IOT platform. With enormous number of users and devices becoming a part of this network, Authentication of communication devices has become more challenging. The work presented in this paper discusses an authentication scheme with reduced overhead based on multi factors, barcodes and One Time Password. The outcome of the experimentation revealed the efficiency of the scheme in terms of guaranteeing enhanced security without compromise in versatility.
