hands-on: PKI in a nutshell

Date: 26.01.2022
Duration: 10:00-17:00
Location: Digitaler Workshop

The ID card, the passport, the electronic health card, smart meter gateways and SSL/TLS work because there is an underlying public key infrastructure (PKI). In the workshop "PKI in a nutshell", we will show the mechanisms, tools, formats and components of a PKI and how they function and work together.

The workshop uses a "bottom-up" approach. With 8 concrete openssl commands a PKI will be built up, concepts and mechanisms of a PKI will be explained based on these commands. The theoretical basics will be explained and knowledge will be imparted by means of practical examples.

The event is aimed at software developers and architects as well as system administrators who work with PKI systems. The whole event will be held in English and is limited to 25 participants.

Contents of the workshop are:

  • Security goals

In Hardware We Trust: Challenges and Opportunities of Hardware Security

The CAST hot topic "In Hardware We Trust: Challenges and Opportunities of Hardware Security" on November 19, 2021 is cancelled. We plan to place the event next year, an exact date is not yet known.

CAST Online Workshops

In these times of COVID-19 restrictions in particular, questions of cyber security remain highly topical. CAST would like to make its contribution and will be organising the CAST workshops online as virtual events from July 2020. This will ensure a continuous exchange of knowledge on current cyber security issues.

The CAST workshops in digital format will be implemented with the open source web conference system BigBlueButton, which is operated with a CAST-owned server located in Darmstadt to ensure data protection.

As soon as the COVID-19 restrictions allow it, CAST will return to the usual workshop format and is already looking forward to welcoming you again personally in Darmstadt.
