If you have a question about this talk, please contact Heidi Howard .

Public-key cryptography is vital to the security of computer systems we use every day. How does it work? How can we use it to ensure our personal security – integrity, confidentiality and privacy? In this lecture I will give an overview of how it works and what we can and do use it for. You should learn what technologies are available to you, what they might achieve and why they work. We will cover concepts including trapdoor functions, identity, trust and perfect forward secrecy. We will cover applications including GPG /PGP, DNSSEC , and monkeysphere.
