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:
It is a Message Digest algorithm which coverts any length of a message into a
unique set of bits. It is widely used MD5 (Message Digest) and 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.
