It is critical to understand the technologies we use to protect data. When trying to convey the importance of digital encryption, questions may arise about how the technology works and why it is important. This presentation explains symmetric and asymmetric cryptography in a nontechnical way. Using hands-on fun aids, we run through an example of elliptic curve cryptography and talk about why this came about and what advantages it gives us. Using presentations of this type to spread security knowledge can ease the job of convincing people to use security technology. This talk will also have a refresher for Fun with Certificates, Part I: RSA. This is a topic specific/intermediate level session.
