Let be a connected, undirected graph without loops and without multiple edges. For a pair of distinct vertices and , a minimum -separating set is a smallest set of edges in whose removal disconnects and . The edge connectivity of , denoted , is defined to be the minimum cardinality of a minimum -separating set as and range over all pairs of distinct vertices in . We introduce and investigate the eavesdropping number, denoted , which is defined to be the maximum cardinality...
