4.8.3.1. IPsec
IPsec is a group of open network security protocols formulated by the IETF, which provide data
source authentication, data encryption, data integrity check, and anti-replay on the IP layer to
ensure the security of data transmission over the Internet. IPsec lowers the risk of data leakage
and interception, ensures data integrity and confidentiality, and protects security of service data
transmission.
The IPsec parameters are described as follows:
•
IKEv1 Policy
•
ID: specifies the ID of an IKEv1 policy.
•
Encryption: specifies the algorithm used to encrypt plain text. Options are 3DES,
DES, AES128, AES192, and AES256.
•
3DES: uses three 64-bit DES keys to encrypt plain text.
•
DES: uses a 64-bit key to encrypt a 64-bit plain-text block.
•
AES: uses a 128-bit, 192-bit, or 256-bit key to encrypt plain text.
o
Hash: specifies the hash algorithm used in the policy. Options are MD5, SHA1,
SHA2-256, SHA2-384, and SHA2-512.
•
