Encryption mode
Description
Auto
This is the recommended option. The KSX II
autonegotiates to the highest level of
encryption possible.
You must select Auto in order for the device
and client to successfully negotiate the use of
FIPS compliant algorithms.
RC4
Secures user names, passwords and KVM
data, including video transmissions using the
RSA RC4 encryption method. This is a
128-bit Secure Sockets Layer (SSL) protocol
that provides a private communications
channel between the KSX II device and the
Remote PC during initial connection
authentication.
If you enable FIPS 140-2 mode and RC4 has
been selected, you will receive an error
message. RC4 is not available while in FIPS
140-2 mode.
AES-128
The Advanced Encryption Standard (AES) is
a National Institute of Standards and
Technology specification for the encryption of
electronic data. 128 is the key length. When
AES-128 is specified, be certain that your
browser supports it, otherwise you will not be
able to connect. See Checking Your
Browser for AES Encryption (on page 196)
for more information.
AES-256
The Advanced Encryption Standard (AES) is
a National Institute of Standards and
Technology specification for the encryption of
electronic data. 256 is the key length. When
AES-256 is specified, be certain that your
browser supports it, otherwise you will not be
able to connect. See Checking Your
Browser for AES Encryption (on page 196)
for more information.
Note: MPC will always negotiate to the highest encryption and will
match the Encryption Mode setting if not set to Auto.
Note: If you are running Windows XP
®
operating system with Service
Pack 2, Internet Explorer

7 cannot connect remotely to the KSX II
using AES-128 encryption.
