Authenticating TCP connections based on public keys

[Christian Stork]

Hi,

I have a potentially naive question so please forgive me if I missed an
obvious answer or if this is not the appropriate list (at least I know
it's not an FAQ): 

Assume I'm running a service for certain peers.  My server knows the
public keys of each peer.  How can I use GPG (or any of its subprojects)
to authenticate an incoming connection based on these public keys?  Is
there a standard for this case?

(I'm interested in keeping the administrative overhead as low as
possible, which is why extra SSL certificates etc. are out of question.)
