Description
ESP Encryption
Algorithm
Set an ESP encryption algorithm when selecting an ESP security protocol.
The router supports the following encryption algorithms:
 DES (Data Encryption Standard): Encrypt64-bit data using a 56-bit key. The last 8 bits
of 64 bits are used for parity check. 3DES (Triple DES) performs encryption using
three 56-bit keys.
 AES (Advanced Encryption Standard): AES128/192/256 indicates performing
encryption using a 128/192/256-bit key.
ESP Encryption Key
Set an ESP encryption key. Both parties of communication must keep the key consistent.
ESP Authentication
Algorithm
Set an ESP authentication algorithm when selecting an ESP security protocol. Set an AH
authentication algorithm when selecting an AH security protocol.
The router supports the following verification algorithms:
 MD5 (Message Digest Algorithm): Generate a 128-bit message digest for a message
to prevent this message from being falsified.
 SHA1 (Secure Hash Algorithm): Generate a 160-bit message digest for a message. It
is more difficult to crack SHA1than to crack MD5.
ESP Outcoming SPI
Set an SPI parameter. Three parameters including SPI, tunnel remote gateway address,
and protocol type jointly identifies one IPSec security ally.
The SPI parameter must be the same as the Incoming SPI value of the remote end of
communication.
ESP Incoming SPI
Set an SPI parameter. Three parameters including SPI, tunnel remote gateway address,
and protocol type jointly identifies one IPSec security ally.
The SPI parameter must be the same as the Outcoming SPI value of the remote end of
communication.
