A Cayley graph or digraph Cay(G, S) is called a CI-graph of G if, for any T subset of G, Cay(G, S) congruent to Cay(G, T) if and only if S-sigma = T for some sigma is an element of Aut(G). The aim of this paper is to characterize finite abelian groups for which all minimal Cayley graphs and digraphs are CI-graphs.
