Pre-Halloween Concert

A Pre-Halloween Concert with Labia and Mephisto System brought me to Zug. To honour the occasion I went dressed as a soldier (with the armor I bought that morning). Needless to say, I was the only one in a costume, unless you consider Goths as people wearing costumes ;). Anyways, it was the second concert from Labia with their new drummer Phillip. This time they presented two new songs which promise interesting times to come :)

Costume Shopping

Last Saturday the City Theater of St. Gallen sold old and used costumes and accessories. A perfect opportunity to find a couple of pieces for the next LARPs.

Not all the things on the picture are my purchases :)

Christian von Aster receiving a Cabaret Price in Leipzig was a very good reason for me to visit this beautiful city. Meeting Mario in the bargain, was another strong reason for the trip. The old city of Leipzig is very nice with beautiful old buildings and almost no traffic. There are many parks as well and I spent almost one day in one of them. The highlight of course was Christian receiving the Cabinet Cabaret Price on Sunday evening. The audience was the opposite of Christian's normal audiences, nevertheless his performance worked and he earned a warm applause.

A big thank you to Mario, who showed me around the city and offered me a place to spend the night.

I'm sure this wasn't my last trip to Leipzig!

Diploma Thesis roundup

It's over, finally! We handed in our diploma thesis at 1pm this afternoon. Normally I'm not the guy who postpones everything to the last second; nevertheless, I only ended up in bed at 4am/3am the last to nights. Compared to others, who have been working straight for 36 hours, that's not too bad though, at least I got a couple of hours of sleep. Still, I'm dog-tired right now.

In case you've been wondering what kept me busy for the last eight weeks you can scan our abstract:

"Implementation of a Certification Authority for ZHW
The awareness of information security has increased tremendously in the last couple of years. The most widely used standard to achieve this security is X.509 which uses certificates with a strict hierarchical trust model. However, to ensure a smooth implementation within an organisation, every individual needs to own such a certificate, the certificates have to be easily accessible and the issuing Certification Authority (CA) must be trusted by all parties.

Thus it is the goal of this thesis to implement a CA for a department of the ZHW and enable the employees to send encrypted and signed email messages. Workflows, processes and different application possibilities will be evaluated, taking into account the needs of the target group.

The result is the IKT Certification Authority, a fully integrated solution which provides certificates to all members of the IKT department and is based on EJBCA, an open source CA. The handling and presentation were adapted to suit the ZHW environment. Certificates are stored on secure crypto tokens which perform all cryptographic operations and are protected by an access code, thus preventing misuse.

Not only defining optimal processes deserved our full attention, but also implementing the user portal was vital. The main reason why implementing security solutions fail is not the missing technology, but inferior usability in the application logic. Therefore we focus on easy usability and well structured workflows. An important part in gaining the trust of users is due to the attractiveness of the portal which adheres to the corporate identity.

The authors firmly hope that this thesis lays a solid foundation for a future extension of the user base to the whole ZHW. Furthermore we hope to show that the implementation of a Public Key Infrastructure is not reserved to big companies and is feasible using open source software."

After rereading the book last week I went to see the movie yesterday evening. I was impressed. It's one of the best novel to screen adaptations I've seen in a long time. Of course there were dozens of things left out, but it stayed extremely true to the spirit of the story and left all the key ingredients in tact. Add to that a splendid cast with stars such as Dustin Hoffman and Alan Rickman and you get an unforgettable experience. However, for someone who hasn't read the book, the story might move too fast and Grenouille might just remain an enigma.

So if you've read the book and liked it: Go see the movie!
