An induced path-cycle double cover (IPCDC) of a simple graph G is a family F Å {F 1 , . . . , F k } of induced paths and cycles of G such that if F i ʝ F j x M, then F i ʝ F j is a vertex or an edge, for i x j, each edge of G appears in precisely two of the F i 's, and each vertex of G appears in pr

We investigate the complexity of the protocol insecurity problem for a ÿnite number of sessions (ÿxed number of interleaved runs). We show that this problem is NP-complete with respect to a Dolev-Yao model of intruders. The result does not assume a limit on the size of messages and supports non-atom
