SA (Security Association)
A Security Association (SA) is the establishment of shared
security attributes between two network entities to support
secure communication. An SA may include attributes such as:
cryptographic algorithm and mode; traffic encryption key; and
parameters for the network data to be passed over the
connection. Establishment of an SA is described in RFC 2408,
the Internet Security Association and Key Management
Protocol.
This page allows you to configure SA.

negotiation in a shorter amount of time. (Not Recommended - Less Secure)
DH Group Select a DH Group from the drop-down menu (Group 1, Group2, Group5 and Group14). As the
