Re: [EAT] [Rats] Rats and EAT

[Yaron Sheffer <[e-mail]>]

I'm a bit surprised that nobody's mentioning the work done by the IETF 
NEA working group <https://datatracker.ietf.org/wg/nea/about/>. Yes, 
it's been some time ago, but the people involved were (to the best of my 
knowledge) involved with the TCG community.

NEA was about desktop machines and NAC rather than mobile devices, but 
hey, by now we should be looking for solutions that encompass both 
technologies!

See this diagram 
<https://wiki.strongswan.org/projects/1/wiki/trustednetworkconnect> on 
how the complex NEA/TNC architecture fits together, including the TPM.

Thanks,
