Thomas, it really depends what you want to protect against. If you
want to encrypt the messages, authenticate servers etc. you can
point to http://www.sni.de/public/aswba/com/en/mail11.htm if you
want to follow the X.400 ('88) approach. If you want to encrypt
and sign the messages end to end give Telenet in Munich a call,
+ 49 89 3607 3120 and ask for Kurt Maier. If you want to connect
a classified internal network to the public network Alcatel Norway
has a B2+ MLS MTA. If so come back to me and I can establish
> The background:
> We are co-working on a security concept for a german bank.
> The bank has a need to protect their X.400 communication.
> There is
> - - server to server communication
> -- by X.400/P1 over TCP(IP (RFC 1006)
> -- by X.400/P1 over OSI TP/X.25
Again what is the problem. Classified to unclassified, internal
to external through the firewall..... or.....?
> - - client-server communiaction
> -- X.400/P7 over TCP(IP (RFC 1006)
> -- Microsoft MAPI with Microsoft-RPC
What is the problem here? Authenticating the users or confidentiallity,
or do you need signatures for non repudiation?
> Any hints are appreciated.
