WebAuthentication Header, AH, Internet Protocol Security IPSec The Authentication Header (AH) is an IPSec protocol that provides data integrity, data origin authentication, and optional anti-replay services to IP. Authentication Header (AH) does not provide any data confidentiality (Data encryption). Authentication Header (AH) is a member of the IPsec protocol suite. AH ensures connectionless integrity by using a hash function and a secret shared key in the AH algorithm. AH also guarantees the data origin by authenticating IP packets.
