Key-Out The encryption key for the outbound policy. The length of the key depends on

the selected encryption algorithm:

• 3DES.

Enter 24 characters.

• None. Key

does not apply.

• DES. Enter 8 characters.

• AES-128.

Enter 16 characters.

• AES-192.

Enter 24 characters.

• AES-256. Enter 32 characters.

SPI-Outgoing The Security Parameters Index (SPI) for the outbound policy. Enter a

hexa

decimal value between 3 and 8 characters (for example, 0x1234).

Integrity Algorithm From the drop-down list, select one of the follo

wing two algorithms to be used in

the VPN header for the authentication process:

• SHA-1.

Hash algorithm that produces a 160-bit digest. This is the default

setting.

• MD

5. Hash algorithm that produces a 128-bit digest.

Key-In The integrity key for the inbound policy. The length of the key depends on the

selected integrity algorithm:

• MD

5. Enter 16 characters.

• SHA-1.

Enter 20 characters.

Key-Out The integrity key for the outbound policy. The length of the key depends on the

selected integrity algorithm:

• MD

5. Enter 16 characters.

• SHA-1.

Enter 20 characters.

Auto Policy Parameters

Note: These fields apply only when you select Auto Policy as the policy type.

SA Lifetime The lifetime of the security association (SA) is th

e period or the amount of

transmitted data after which the SA becomes invalid and needs to be

renegotiated. From the drop-down list, select how the SA lifetime is specified:

• Seconds. In the SA Lifetime fiel

d, enter a period in seconds. The minimum

value is 300 seconds. The default setting is 3600 seconds.

• KBy

tes. In the SA Lifetime field, enter a number of kilobytes. The minimum

value is 1920000 KB.

Encryption Algorithm From the drop-down list, select one of the

following five algorithms to negotiate

the security association (SA):

• 3DES. T

riple DES. This is the default algorithm.

• None. No

encryption algorithm.

• DES. Dat

a Encryption Standard (DES).

• AES-128.

Advanced Encryption Standard (AES) with a 128-bit key size.

• AES-192. AES with a

192-bit key size.

• AES-256. AES with a 256-bit key size.
