[ndnSIM] Content Store problem

[John Baugh]

I'm not clear on exactly what you're asking, but perhaps you could
implement your own Policy (as a subclass/derived class of nfd::cs::Policy)
-> https://ndnsim.net/2.1/doxygen/classnfd_1_1cs_1_1Policy.html

You could use one of the protected members (override them in your subclass)
to do the additional verification / authentication:

virtual void  doAfterInsert

Hope this helps.
