DESCRIPTION
Press [SPACE BAR] to choose from Main or Aggressive and then press [ENTER].
See earlier for a discussion of these modes. Multiple SAs connecting through a
secure gateway must have the same negotiation mode.
PSK Prestige gateways authenticate an IKE VPN session by matching pre-shared keys.
Pre-shared keys are best for small networks with fewer than ten nodes. Enter your
pre-shared key here. Enter up to 31 characters. Any character may be used, includ-
ing spaces, but trailing spaces are truncated.
Both ends of the VPN tunnel must use the same pre-shared key. You will receive a
"PYLD_MALFORMED" (payload malformed) packet if the same pre-shared key is
not used on both ends.
When DES is used for data communications, both sender and receiver must know
the same secret key, which can be used to encrypt and decrypt the message or to
generate and verify a message authentication code. Prestige DES encryption algo-
rithm uses a 56-bit key.
Triple DES (3DES), is a variation on DES that uses a 168-bit key. As a result, 3DES
is more secure than DES. It also requires more processing power, resulting in
slightly increased latency and decreased throughput.
Press [SPACE BAR] to choose from 3DES or DES and then press [ENTER].
