PROGRAM 


10.45 - 11.30 hrs.: 
Vladimir Balakirsky (Institute for Experimental Mathematics, Essen,
Germany), 
On the secrecy of a common knowledge created by correlated observations
and transmission over helping channels. 
Abstract: We consider the following scenario. Two individuals receive
correlated observations from a source and want to construct a coinciding
realization of some random process. The individuals exchange a pair of
messages at monologues. There is also an eavesdropper who receives
exchanged messages, but does not have observations of individuals. We
characterize the resulting processes constructed by the individuals and
the eavesdropper by their entropies. Possible solutions to the problem
of maximizing the difference between the entropy of the probability
distribution constructed by individuals and the eavesdropper are
presented for some numerical examples.
