IPsec Authentication
Background
As networks develop, network security has become an increasing concern. Internet Protocol Security (IPsec) authentication can be used to authenticate RIPng packets. The packets that fail to be authenticated are discarded, which prevents data transmitted based on TCP/IP from being illegally obtained, tampered with, or attacked.
Implementation
IPsec has an open standard architecture and ensures secure packet transmission on the Internet by encrypting packets. RIPng IPsec provides a complete set of security protection mechanisms to authenticate RIPng packets, which prevents devices from being attacked by forged RIPng packets.
IPsec includes a set of protocols that are used at the network layer to ensure data security, such as Internet Key Exchange (IKE), Authentication Header (AH), and Encapsulating Security Payload (ESP). The three protocols are described as follows:
- AH: A protocol that provides data origin authentication, data integrity check, and anti-replay protection. AH does not encrypt packets to be protected.
- ESP: A protocol that provides IP packet encryption and authentication mechanisms besides the functions provided by AH. The encryption and authentication mechanisms can be used together or independently.
AH and ESP can be used together or independently.
Benefits
RIPng IPsec offers the following benefits:
- Improves carriers' reputation and competitiveness by preventing services from being tampered with or attacked by unauthorized users.
- Ensures confidentiality and integrity of user packets.
