In this paper we show how to divide data D into n pieces in such a way that D is easily reconstructable from any k pieces, but even complete knowledge of k-1 pieces reveals absolutely no information about D. This technique enables the construction of robust key management schemes for cryptographic systems that can function security breaches expose all but one of the remaining pieces.
