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 used 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.



SHA: SHA (Secure Hash Algorithm) takes a message less than the

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.



SHA: SHA (Secure Hash Algorithm) takes a message less than the

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.
