Security
New security features have been added to LNS since Release 3.0 to protect against
unwanted access to sensitive data. In LNS 3.07, Echelon introduced the OpenLDV
xDriver to support a new class of remote network interfaces, including the
i
.LON 10
Ethernet Adapter and the
i
.LON 100 Internet Server. The TCP/IP link to those new
interfaces includes MD5 authentication and sequence numbering to prevent
unauthorized access or replay attacks on the link. In LNS Turbo Edition, RC4 encryption
is also used when passing LonWorks authentication keys over the link.
For more information on the OpenLDV xDriver, see the OpenLDV Programmer’s Guide,
