App Revocation Checking: Why is this still so hard?


Certificate revocation checking is a cornerstone to the security of the public key infrastructure ecosystem, but it is unknown how well mobile applications are conducting certificate revocation checking.

I conclude this talk by discussing some reasons it is currently difficult for developers to properly check for revocations.
