Abstract
Email encryption techniques have been available for
more than a decade, yet none has been widely deployed.
The problems of key generation, certification,
and distribution have not been pragmatically addressed.
We recently proposed a method for implementing a
Lightweight Public Key Infrastructure (PKI) for email
authentication using recent developments in identitybased
cryptography and today's existing Internet infrastructure.
While this solution works well for email authentication,
email encryption exhibits a different threat model
that requires special treatment. In this work, we discuss
how to achieve email encryption and present a realistic
deployment and adoption process, while respecting the
current functionality and expectations of email.
