Abstract |
The need to protect information from
theft or unauthorized modification necessitates the sharing of rights of access to it.
Proper differentiation of access to information
means that the group of unpermitted participants
gets no information about the secret, and any
permitted one can restore it. The article dwells
on the hypothesis which is going to be proved on the
example of Fano matroid, as well as in the
course of further research and other matroids.
