Two extensions of the partial order reduction algorithm of Clarke, Jha and Marrero are presented. The proposed algorithms are suitable for branching security protocols, e.g. optimistic fair contract signing schemes. The first extension is proved to generate a reduced state space which is branching bisimilar to the full state space, while the second extension generates a state space that is trace equivalent...

Once a BCMS is in place, the corresponding risks can be insured against. The BS 25999 certificate can serve as proof of implementation. It requires defined business continuity plans (BCP).
