STEED — Usable End-to-End Encryption

Werner Koch, Marcus Brinkmann

White Paper, g10code GmbH


End-to-end e-mail encryption is still ignored by almost all users. The mails are left in the clear in the mailboxes of the web mail providers, where they are frequently collected by attackers and lead to an escalation of the attack due to the sensitivity of the mail content. We suggest a new and simplified infrastructure to protect mail that is compatible with OpenPGP and S/MIME and relies on an easy-to-use trust model without a central administration.
