User's Manual

Security Protocol:
Select the security protocol to be used. Options include:
 AH: AH (Authentication Header) provides data origin authentication,
data integrity and anti-replay services.
 ESP: ESP (Encapsulating Security Payload) provides data encryption
in addition to origin authentication, data integrity, and anti-replay
services.
AH Authentication:
Select the algorithm use
d to verify the integrity of the data for AH
authentication. Options include:
 MD5: MD5 (Message Digest Algorithm) takes a message of arbitrary
length and generates a 128-bit message digest.
 SHA1: SHA1 (Secure Hash Algorithm) takes a message less than
2^64 (64th power of 2) in bits and generates a 160-bit message digest.
ESP
Authentication:
Select the algorithm used to verify the integrity of the data for ESP
authentication. Options include:
 MD5: MD5 (Message Digest Algorithm) takes a message of arbitrary
length and generates a 128-bit message digest.
 SHA1: SHA1 (Secure Hash Algorith
m) takes a message less than
2^64 (64th power of 2) in bits and generates a 160-bit message digest.
ESP Encryption:
Select the algorithm used to encrypt the data for ESP encryption. Options
include:
NONE: Performs no encryption.
DES: DES (Data Encryption Standard) encrypts a 64-bit block of plain text
with a 56-bit key. The key should be 8 characters.
3DES: Triple DES, encrypts a plain text with 168-bit key. The key should be
24 characters.
AES128: Uses the AES algorithm and 128-bit key for encryption. The key
should be 16 characters.
AES192: Uses the AES algorithm and 192-bit key for encryption. The key
should be 24 characters.
AES256: Uses the AES algorithm and 256-bit key for encryption. The key
should be 32 characters.
