In Root we trust (no this is not a DNS talk)

Date/Time: February 20, 2019, 6:30 PM to 8:30 PM EST
Location: Room 128, St. James Campus - Building A, George Brown College, 200 King Street East, Toronto, ON, M5A 3W8


What do airplanes, TSA pre-check, credit cards, Windows Updates, and HTTPS all have in common? They all rely on the use of digital certificates as a basis for the security they provide.

In this talk Pavan and Lisa will share their expertise on what a digital certificate is, what they can be used for, and why we trust them (or not trust them in some cases...). They will cover the fundamentals of Public Key Infrastructure (PKI) and shed light on the critical role that Root Certification Authorities (CAs) play in all of our lives.

This talk is aimed at those who are onboard for HTTPS everywhere but want to dive into the nuts and bolts of how certificates work and understand the broader applications of PKI.

Recently, Pavan’s focus has shifted to Public Key Infrastructure (PKI) and the Certification Authorities (CAs) that issue publicly trusted TLS certificates. He has performed audits of both public and enterprise CAs and has been an official witness to several root key generation ceremonies both in Canada and internationally.
