    abstract =  {This document defines a new HTTP header field, named Expect-CT, that allows web host operators to instruct user agents to expect valid Signed Certificate Timestamps (SCTs) to be served on connections to these hosts. Expect-CT allows web host operators to discover misconfigurations in their Certificate Transparency deployments and ensure that misissued certificates accepted by UAs are discoverable in Certificate Transparency logs.},
