Phase 1
Encryption
Algorithm
Select
3DES
,
AES128
or
AES256
from the drop-down list box.
When you use one of these encryption algorithms for data communications, both the
sending device and the receiving device must use the same secret key, which can be
used to encrypt and decrypt the message or to generate and verify a message
authentication code. The
DES
encryption algorithm uses a 56-bit key. Triple DES
(
3DES
) is a variation on
DES
that uses a 168-bit key. As a result,
3DES
is more secure
than
DES
. It also requires more processing power, resulting in increased latency and
decreased throughput.
This implementation of
AES
uses a 128-bit key and a 256-bit key.
AES
is faster than
3DES
.
