Maja is a curious and ambitious human who enjoys working on complex systems and shows strong perseverance in understanding how things actually work. For the last 1.5 years she's been working as software developer on IRMA, focusing on the IRMA server.
IRMA is a system in which you are in control of sharing specific personal properties (aka attributes) such as your age, address and gender which are stored in the IRMA app on your phone. Technically, IRMA is a set of free and open source software projects implementing the Idemix attribute-based credential scheme. Although the Idemix credential system has been around for a while it is still relevant today. In this talk, we walk you through the crypto behind Idemix, explain how it works, why it is safe and give you the means to understand Gabi, the Go implementation of Idemix that is used in IRMA.
