Abstract: . Boneh and Venkatesan have recently proposed a polynomial time algorithm for recovering a "hidden" element # of a finite field IFp of p elements from rather short strings of the most significant bits of the remainder modulo p of #t for several values of t selected uniformly at random from IF # p . We use some recent bounds of exponential sums to generalize this algorithm to the case when t is selected from a quite small subgroup of IF # p . Namely, our results apply to subgroups of size at...
