Based on this paragraph...
"If untrusted links are used for transit, which is NOT RECOMMENDED,
   and therefore need to carry HNCP and Babel traffic, then HNCP and
   Babel MUST be secured using an upper-layer security protocol.  While
   both HNCP and Babel support cryptographic authentication, at the time
   of writing no protocol for autonomous configuration of HNCP and Babel
   security has been defined."

...one might recommend starting with "an upper-layer security protocol"
such as CMS, COSE, JOSE or some other layer-3 encapsulation.
