  Correlated sources are present in communication systems where protocols
ensure that there is some predetermined information for sources. Here
correlated sources across an eavesdropped channel that incorporate a
heterogeneous encoding scheme and their effect on the information leakage when
some channel information and a source have been wiretapped is investigated. The
information leakage bounds for the Slepian-Wolf scenario are provided.
Thereafter, the Shannon cipher system approach is presented. Further, an
implementation method using a matrix partition approach is described.
