In linux kernel since version 2.6.12  
Support for IPsec AH (Authentication Header).

AH can be used with various authentication algorithms. Besides
enabling AH support itself, this option enables the generic
implementations of the algorithms that RFC 8221 lists as MUST be
implemented. If you need any other algorithms, you'll need to enable
them in the crypto API. You should also enable accelerated
implementations of any needed algorithms when available.

If unsure, say Y.
