Provided you know the time of the transaction, the web server logs will give
you details of the IP address all the web transactions are coming from. You
can find who owns this IP address via the Ripe (www.ripe.net), Arin
(www.arin.net) or Apnic (www.apnic.net) websites.

>From this you can find which ISP this address belongs to, and that ISP can
verify who was using that IP address at the time. How much assistance you
receive from each ISP will vary.

That may give you sufficient information to press a case against the person
who alleges they didn't access your website, but IANAL. 

I'm not sure what you mean about information being signed with a given key.
Do you mean a personal key like a digital signature, or do you mean the SSL
key?

The teaching of evolution as a proven fact rather than a theory has done
more harm to scientific progress than anything else in history.
