LABEL

DESCRIPTION

Encryption

Algorithm

Select

DES

,

3DES

or

AES

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.

AES

is faster than

3DES

.

Authentication

Algorithm

Select

SHA1

or

MD5

from the drop-down list box.

MD5

(Message Digest 5) and

SHA1

(Secure Hash Algorithm) are hash algorithms used to authenticate packet

data. The

SHA1

algorithm is generally considered stronger than

MD5

, but is slower.

Select

MD5

for minimal security and

SHA-1

for maximum security.

SA Life Time

(Seconds)

Define the length of time before an IKE SA automatically renegotiates in this field. It
may range from 60 to 3,000,000 seconds (almost 35 days).

A short SA Life Time increases security by forcing the two VPN gateways to update
the encryption and authentication keys. However, every time the VPN tunnel
renegotiates, all users accessing remote resources are temporarily disconnected.

Key Group You must choose a key group for phase 1 IKE setup.

DH1

(default) refers to Diffie-

Hellman Group 1 a 768 bit random number.

DH2

refers to Diffie-Hellman Group 2 a

1024 bit (1Kb) random number.

Phase 2

Active Protocol Use the drop-down list box to choose from

ESP

or

AH

.

Encryption

Algorithm

This field is available when you select

ESP

in the

Active Protocol

field.

Select

DES

,

3DES

,

AES

or

NULL

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

. It also requires more processing power, resulting in increased

latency and decreased throughput. This implementation of AES uses a 128-bit key.

AES

is faster than

Select

NULL

to set up a tunnel without encryption. When you select

NULL

, you do

not enter an encryption key.
