Email Security & Development By: Yosef Gamble CS 325 https://commons.wikimedia.org/wiki/File:Crypto_key.svg
Table of Contents Email Security Flaws Encryption Techniques Public key Infrastructure (PKI) Pretty Good Privacy (PGP) Application Future Development
Email Security Flaws Email is sent in plain text. Email uses outdated protocol, Simple Mail Transfer Protocol (SMTP). Includes a header full of revealing metadata. Can easily become intercepted.
Encryption Techniques - PKI Public Key Infrastructure Introduced public/private key encryption using certificates Relied on Third-Party vendors Widely used in Corporate environment https://en.wikipedia.org/wiki/Public_key_infrastructure#mediaviewer/File:Public-Key-Infrastructure.svg
Encryption Technique - PGP Pretty Good Privacy Decentralised version of PKI Removed Third-Party Involvement Uses ‘Web of Trust’ authentication https://www.sandboxgeneral.com/?p=974
Applications GNU Privacy Guard (GnuPG) Hushmail Lavabit, Silent Circle, & PrivateSky Third-Party Plugins Webmail https://en.wikipedia.org/wiki/GNU_Privacy_Guard#mediaviewer/File:Gnupg_logo.svg
Future Development Focus on End-to-End Email Encryption and Usability Dark Mail Project Extensible Messaging and Presence Protocol (XMPP) http://www.darkmail.info
Conclusion Email Security Flaws Encryption Techniques Public key Infrastructure (PKI) Pretty Good Privacy (PGP) Application Future Development
