Clearly, a scheme as described above cannot be deterministic. Thus, we introduce a probabilistic coding scheme which, in addition to the standard coding theoretic requirements, has the feature that any constant fraction of the bits in the (randomized) codeword yields no information about the message being encoded. This coding scheme is also used to obtain efficient constructions for the Wire-Tap Channel Problem.
