+ % To explain the paper's contribution we can simply break down the title:
+ % privacy-preserving and incrementally deployable support for Certificate
+ % Transparency in Tor.
+ %
+ % To make a long story short, Tor Browser does not support Certificate
+ % Transparency. The reason why you want to do that is because it makes it
+ % possible to detect if visited websites are being impersonated or not.
+ %
+ % For example, an attacker may want to impersonate a website to steal a
+ % user's credit card number. It is also helpful to de-anonymize a Tor user.
+ %
+ % So, our work focus on adding support for Certificate Transparency in Tor
+ % Browser. We do that while focusing on two key properties.
+ %
+ % The proposed solution should be _privacy-preserving_. We achieve this
+ % because of and how we use Tor.
+ %
+ % The proposed solution should also be incrementally-deployable, and in the
+ % end have a stronger threat model than current Certificate Transparency
+ % deployments in Chrome and Safari that trust so-called CT logs blindly.
+ %
+ % In more detail, our incrementally-deployable design goes from:
+ % pairs of CT logs that are trusted blindly, to
+ % at least one CT log is trusted blindly, to
+ % no CT log that is trusted blindly.
+ %
+ % It is fair to say that we have a strong threat model where the attacker
+ % even has a zero-day exploit against Tor Browser. In spite of this very
+ % strong threat model, the involved performance overhead is modest.
+ %
+ % For more detail, please refer to our paper and/or watch the presentation.
