Which cryptographic process provides origin confidentiality, integrity, and origin authentication for packets?

ESP provides confidentiality by encrypting the packet payload, along with data integrity and data origin authentication, making it the correct choice for all three services requested.

AH provides data integrity and data origin authentication, but it does *not* provide confidentiality (encryption).

IKEv1 is a key exchange protocol used to establish IPsec Security Associations, not to directly provide confidentiality, integrity, and authentication for data packets.

IKEv2 is a key exchange protocol used to establish IPsec Security Associations, not to directly provide confidentiality, integrity, and authentication for data packets.
