Subject: Re: [dss-dev] DSS services and European Signature law

Hi Pim,

as this is a difficult topic I used Detlef as my backup expert ;-)
Detlef confirmed my quick guess that each an every component of a 
DSS-based SSCD needs to evaluated on its own. Usually that's would 
require an evaluation of a hardware component ( hopefully a smartcard 
with a testimonial ) and the software artifacts. But an EAL 4+ 
evaluation of a software component would be extremely expensive and 
would need a re-evaluation with every minor release .. would presume 
this to be overkill.

Don't think that's a way to ...

Hello Andreas,

Thanks a lot for your response.  You are right that there are many more
issues to consider to be able to state whether or not a DSS 
meets EAL 4+.  To rephrase my question, more precisely, assume we have 
device that is certified to meet the requirements of CWA 14169 that has 
"trusted path" to a local user interface. For instance, it could be a
hardware device that uses the keyboard and monitor of a computer as 
interface.  Now assume an alternative device that is similar in all 
except that it can be accessed from remotely using DSS.  Would this 
qualify as an SSCD?
