Query: Security Analysis of two Distance-Bounding Protocols   In this paper, we analyze the security of two recently proposed distance
bounding protocols called the Hitomi and the NUS protocols. Our results show
that the claimed security of both protocols has been overestimated. Namely, we
show that the Hitomi protocol is susceptible to a full secret key disclosure
attack which not only results in violating the privacy of the protocol but also
can be exploited for further attacks such as impersonation, ma?a fraud and
terrorist fraud attacks. Our results also demonstrates that the probability of
success in a distance fraud attack against the NUS protocol can be increased up
to (3/4)^n and even slightly more, if the adversary is furnished with some
computational capabilities.
