Query: Mobile Encryption Gateway (MEG) for Email Encryption   Email cryptography applications often suffer from major problems that prevent
their widespread implementation. MEG, or the Mobile Encryption Gateway aims to
fix the issues associated with email encryption by ensuring that encryption is
easy to perform while still maintaining data security. MEG performs automatic
decryption and encryption of all emails using PGP. Users do not need to
understand the internal workings of the encryption process to use the
application. MEG is meant to be email-client-agnostic, enabling users to employ
virtually any email service to send messages. Encryption actions are performed
on the user's mobile device, which means their keys and data remain personal.
MEG can also tackle network effect problems by inviting non-users to join. Most
importantly, MEG uses end-to-end encryption, which ensures that all aspects of
the encrypted information remains private. As a result, we are hopeful that MEG
will finally solve the problem of practical email encryption.
