Security challenges arise when devices (such as, for example, smart meters) that are deployed to Internet of things (IoT) networks employ only a certificate for authentication. A certificate is a static authentication method, and if the security mechanism of a single node is cracked then the security mechanism of the entire IoT network will be broken. At the same time, since the security certificates of all of the nodes are the same it is difficult to isolate and remove the compromised nodes. To address such challenges, techniques are presented herein that support an innovative multi-factor authentication facility. Among other things, the presented techniques leverage the characteristics of a mesh network and are compatible with existing devices (e.g., smart meters).
