Field Description
and opinion at the time of creating this User Guide. In particular,
the quality of the algorithms is subject to relative aspects and
may change due to mathematical or cryptographic develop-
ments.
DH Group The Diffie-Hellman group defines the parameter set used as the
basis for the key calculation during phase 1. "MODP" as sup-
ported by bintec devices stands for "modular exponentiation".
Possible values:
• . >": During the Diffie-Hellman key calculation, mod-
ular exponentiation at 768bits is used to create the encryption
material.
• >": During the Diffie-Hellman key calculation,
modular exponentiation at 1024 bits is used to create the en-
cryption material.
• ' >": During the Diffie-Hellman key calculation,
modular exponentiation at 1536 bits is used to create the en-
cryption material.
Lifetime Create a lifetime for phase 1 keys.
As for RFC 2407, the default value is eight hours, which means
the key must be renewed once eight hours have elapsed.
The following options are available for defining the lifetime:
Input in Seconds: Enter the lifetime for phase 1 key in seconds.
The value can be a whole number from 0 to 2147483647. The
default value is .
Input in kBytes: Enter the lifetime for phase 1 keys as amount
of data processed in kBytes. The value can be a whole number
from 0 to 2147483647. The default value is .
The standard value as per RFC is used seconds and
Kbytes are entered.
Authentication Method Only for Phase-1 (IKE) Parameters
Select the authentication method.
