Netgear FVS318N 사용자 설명서

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

Integrity Algorithm

From the drop-down list, select one of the following 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.

•  MD5. 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:

•  MD5. 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:

•  MD5. Enter 16 characters.

•  SHA-1. Enter 20 characters.

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

SA Lifetime

The lifetime of the security association (SA) is the 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 field, enter a period in seconds. The minimum 

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

• KBytes. 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. Triple DES. This is the default algorithm.

•  None. No encryption algorithm.

•  DES. Data 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.
