Hi,Fabio, - Assuming that you intend to deal with IPV4, I suggest that you will start by looking at the ah4.ko module sources, which are in net/ipv4/ah.c, especially at the ah_output() and the ah_input() methods.
(for ipv6 there are the ah6.c in net/ipv6). - May I ask: are you aware that the Authentication Header protocol deals only with authentication and not with encryption? and as a result, the ESP protocol, which supports authentication and also, when needed, encryption, is much more widely used?
