Key server security considerations / Certification Authorities

[christian@jacken.net]

Hello,

how do I prevent someone else to create a key in my name and to send it to a
key server to mislead third parties?

And is anyone aware of a Trust Center (Certification Authority) which would
sign a GnuPG key created by me?

I visited signtrust.deutschepost.de for example, however they only sign keys
that they have created, and deliver the keys on chipcards which work with a
PIN code.

Thanks,
