IoT Security Research

See this page for research in our group on IoT and Cyber-Physical Systems. Some recent work includes research on adversarial machine learning (CVPR 2008), defense mechanisms to make OAuth tokens at trigger-action cloud services such as IFTTT less risky (NDSS 2018), security analysis of SmartThings IoT application platform (IEEE S&P 2016), and ContexIoT, an automatic IoT app patching mechanism to help enforce context-based permissions (NDSS 2017). .

Data Privacy Research

  • With Facebook privacy issues in the news, revisit our 2008 CSCW paper that warned of some of the risks of access to social network data and also outlined some defense strategies: Social Networks and Context-Aware Spam
  • FlowFence paper (Usenix Security 2016) that proposes the Quarantined Modules mechanism for permitting safer computing on flow-sensitive data on hubs or servers:
