Data Encryption Offload
About Data
Encryption
The 3Com Firewall PC Card with 10/100 LAN performs data encryption processing
offloads in Windows 2000 and Windows XP, which means that the network card,
the 3Com Firewall PC Card with 10/100 LAN, rather than the operating system
does the encryption.
Encryption processing is handled entirely by the 3XP processor on the network
card. The 3XP processor enables true end-to-end network security at the data
capacity of the connected network cable without sacrificing performance.
The data encryption offload capability of the 3Com Firewall PC Card with 10/100
LAN is disabled when you first unpack it. U.S. law requires that users be certified
to use certain data encryption products.
The 3Com Firewall PC Card with 10/100 LAN uses Internet Protocol Security
(IPSec) encryption, which is a framework of open standards for ensuring secure
private communications over IP networks. IPSec ensures confidentiality, integrity,
access control, and authenticity of data communications across a public IP
network.
Offloading Encryption
Processing
You can configure two or more computers running Windows 2000 and Windows
XP to perform IPSec encryption by changing the local security setting in the
operating system. With most non-3Com Firewall PC Card with 10/100 LAN, all the
IPSec processing is done by the host central processing unit (CPU), which
significantly diminishes CPU performance. The 3Com Firewall PC Card with
10/100 LAN can offload all the encryption processing from the host CPU, thereby
freeing the CPU to work on other tasks.
For two or more computers running non-Windows 2000 or Windows XP
operating systems, IPSec encryption is provided by third-party applications. The
3Com Firewall PC Card with 10/100 LAN does not provide IPSec encryption
offloading for those operating systems.
