I am from the German chapter.
My main areas are application security in Enterprise Content Management and cryptography.
I work as a chair of the LTANS WG at the IETF and some local expert groups in Germany.
If you like you can meet me at the IETF conferences or at some of the European Security Conferences.
Next conference in Europe, I volunteered as a speaker will be ISSE, 25-27 September 2007, Warsaw.
Or just send me an email or give me a call. ;-)
