in this paper, the security of a distance bounding protocol is analyzed which has been recently proposed by jannati and falahati (so-called jf). we prove that an adversary can recover key bits of jf protocol with probability of “1” while the complexity of attack is “2n” runs of protocol. in addition, we propose an improved protocol and prove that the improved protocol is resistant to mafia frau...

Armed conflict has a major impact on child health throughout the world. One in six children worldwide lives in an area of armed conflict and civilians are more likely to die than soldiers as a result of the conflict. In stark contrast to the effect on children, the international arms trade results in huge profits for the large corporations involved in producing arms, weapons and munitions. Arme...

We consider the framework of stochastic multi-armed bandit problems and study the possibilities and limitations of forecasters that perform an on-line exploration of the arms. A forecaster is assessed in terms of its simple regret, a regret notion that captures the fact that exploration is only constrained by the number of available rounds (not necessarily known in advance), in contrast to the ...

This issue brief provides a brief overview of the legal, political, and operational frameworks protecting children from the effects of armed conflict, notably from violations by nonstate armed groups. It explores some of the limitations of these frameworks and their mechanisms, and then discusses ways to maximize the comparative advantages of different actors when engaging nonstate armed groups...

Moreover, to win the trust and support of the larger polity, the armed services must be widely perceived as serving important social needs. Without this trust and support, the armed forces will not get the resources they need to fu...
