Which of the following methods are used in IPsec to ensure secure transmission of service data on the network through encryption and authentication?

Show Suggested Answer Hide Answer
Suggested Answer: A, D

IPsec uses authentication headers (AHs) and encapsulating security payloads (ESPs) to ensure secure transmission of service data on the network. AHs provide authentication and integrity verification for the sender and the receiver, while ESPs provide encryption and optional authentication for the data.

I vaguely remember something about rejecting old packets being crucial for security, so I think option B might also be relevant.

I think options A and C are about identity verification, which is definitely part of IPsec, but I can't recall if both are necessary.

I remember studying that IPsec uses both encryption and authentication, but I'm not sure which specific methods apply here.
