<br><font size=2 face="sans-serif">Yes, we'll still have the IDS call today
at 1:00 PM EST. I have not seen an updated NAP Binding spec, but
we can discuss the Secure Time definition (below) and Microsoft's responses
to our questions that I forwarded earlier.</font>

<br><font size=2 face="sans-serif">Secure Time: This attribute signifies
that the time source used to set the device's clock(s) is considered a
trusted source. Many security mechanisms rely on accurate time to
enforce security. Examples include validity periods on X.509 certificates
and Kerberos Tickets. As such, it is important to know that the device's
internal clock(s) acquire time in a secure manner. If the time source
is not secure, it could lead to denial of service (set time outside the
validity period) and/or allow unauthorized access (set time to within validity
period.) There are several ways to acquire the time including Network
Time Protocol (NTP) and explicitly set by the user via some user interface.
NTP has the ability to utilize encryption and integrity checks using
pre-shared keys. The user interface to the clock can be protected
using passwords. It is important to note that RTCs are often used
in devices and may utilize a bus structure, such as I2C. In such
cases, the bus used MUST NOT be accessible externally from the device.</font>
