  The Internet of Things (IoT) is a new computing paradigm that spans wearable
devices, homes, hospitals, cities, transportation, and critical infrastructure.
Building security into this new computing paradigm is a major technical
challenge today. However, what are the security problems in IoT that we can
solve using existing security principles? And, what are the new problems and
challenges in this space that require new security mechanisms? This article
summarizes the intellectual similarities and differences between classic
information technology security research and IoT security research.
