Abstract
Suppose that Alice and Bob define their coordinate axes differently, and the change of reference frame between them is given by a probability distribution mu over SO(3). We show that this uncertainty of reference frame is of no use for bit commitment when mu is uniformly distributed over a (sub)group of SO(3), but other choices of mu can give rise to a partially or even asymptotically secure bit commitment.
