This talk will explain the basic building blocks of cryptography in a manner that will (hopefully) be understandable by everyone, in particular by a non-technical audience. The talk will not require any understanding of maths or computer science.
This talk will cover the following topics:
<li>What is encryption and what does it do?</li>
<li>What are the different kinds of encryption?</li>
<li>What is authenticity? Are authenticity and encryption related?</li>
<li>How can authenticity be achieved?</li>
<li>What are certificates for?</li>
<li>What is TLS and what does it do?</li>
While covering the above topcis, I will <em>not</em> explain the technical details of common cryptographic schemes (like RSA, AES, HMAC and so on), in order to avoid keep this talk accessible to a broad audience.
