Chapter 4: Configuration

Advanced Option

This function is only available after completely creating an IPSec account. Click Advanced Option to

change the following settings:

IKE (Internet key Exchange) Mode: Select IKE mode to Main mode or Aggressive mode. This IKE

provides secured key generation and key management.

IKE Proposal:

Hash Function: This is a Message Digest algorithm which coverts any length of a message into a unique

set of bits. You can use either MD5 (Message Digest) or SHA-1 (Secure Hash Algorithm) algorithms.

SHA1 is more resistant to brute-force attacks than MD5, however it is slower.

~ MD5: A one-way hashing algorithm that produces a 128−bit hash.

~ SHA1: A one-way hashing algorithm that produces a 160−bit hash

Encryption: Select the encryption method from the pull-down menu. There are several options, DES,

3DES and AES (128, 192 and 256). 3DES and AES are more powerful but increase latency.

~ DES: Stands for Data Encryption Standard, it uses 56 bits as an encryption method.

~ 3DES: Stands for Triple Data Encryption Standard, it uses 168 (56*3) bits as an encryption

method.
