Mutual Authentication for IoT in the Context of Fog Computing

The authentication of restricted memory devices has major problems because memory consumption is high when applied with other protocols that have the purpose of mutual authentication. This article proposes an authentication model that validates mutually the parties in an Internet of Things environment applied in the context of Fog Computing. Through the hypothetic-deductive methodology, the deductions and hypotheses are presented for the formal proof of the new proposed method. The results achieved in the research show that the approach of the authentication mechanism is optimized, the prototype was validated in the AVISPA protocol evaluation tool and in a restricted memory controlled environment in a context of Fog Computing. However, this work is more appropriate in Fog Computing environments because there are no route changes as in Cloud Computing.
