research overview

  • With the emergence of public cloud computing and the internet of things, modern computer architectures are inadequate to address the security and privacy concerns of users. In this work, we look for innovative solutions to secure the computer from the hardware up. By designing the computer architecture with security as a number one priority, along with performance, we can provide additional guarantees about the security and privacy of data. In addition we look to reinforce the public' resilience to polluted information considering that social media has now taken on a new role with respect to democracy around the world.
