+    summary={%
+      One deployment challenge of Certificate Transparency is to ensure that
+      monitors and end-users are engaged in gossip-audit protocols.  This is
+      particularly difficult for end-users because such engagement can harm
+      privacy.  For example, verifying that a certificate is included by
+      fetching an inclusion proof from a log reveals which website was visited.
+      We propose a gradual roll-out of Certificate Transparency in Tor Browser
+      that preserves privacy \emph{due to} and \emph{how we use} the anonymity
+      network Tor.  The complete design holds log operators accountable for
+      certificates they promise to append by having Tor relays fetch inclusion
+      proofs against the same view agreed upon by directory authorities in Tor's
+      consensus.  Found issues (if any) are reported to trusted auditors.  The
+      incremental design side-steps much of the practical deployment effort by
+      replacing the audit-report pattern with cross-logging of certificates in
+      independent logs, thus assuming that at least one log is honest as opposed
+      to no log in the complete design.  All Tor Browser needs to do is verify
+      log signatures and then submit the encountered certificates to randomly
+      selected Tor relays.  Such submissions are probabilistic to balance
+      performance against the risk of eventual detection of log misbehavior.
+      Processing of the submitted certificates is also randomized to reduce
+      leakage of real-time browsing patterns, something Tor Browser cannot do on
+      its own due to criteria like disk avoidance and the threat model for
+      wanting Certificate Transparency in the first place.  We provide a
+      security sketch and estimate performance overhead based on Internet
+      measurements.
