Authentication Header
Ensures connectionless integrity by using a hash function and a secret shared key.
Also guarantees the data origin by authenticating IP packets.
Provides origin authenticity through source authentication, data integrity through hash functions and confidentiality through encryption protection for IP packets.
Encapsulating Security Payload
