Query: Private Queries on Public Certificate Transparency Data   Despite increasing advancements in today's information exchange
infrastructure, the preservation of user data and privacy still remains a
problem. Both insecure baselines and secure solutions leak user data. For
example, Certificate Transparency (CT) promises significant security
improvements to existing Public Key Infrastructure solutions that up-to-now
have solely relied on the Certificate Authority hierarchy. CT provides a robust
auditing layer and transparency solution to quickly detect such compromises,
but introduces the requirement that client browsers interact with third-party
servers when validating a site certificate. In the existing CT system, these
requests leak information about each user's browsing habits to the hosting
server. It is not a stretch to think that this valuable data could be collected
and exploited, as corporations and governments have plenty of financial and
political incentive to do so. In this project, we seek to address this problem
by using an oblivious file sharing system with strong anonymity properties, to
provide a more scalable, performant solution to privacy-preserving queries.
