摘要：Methods and apparatus are provided for secure distribution and storage ofdata using N channels. An input data sequence, X, is distributed using a plurality, N, of

channels. In one embodiment, the input data sequence, X, is split into N subsequences;and the N subsequences are encoded into N bit streams using a set of Slepian-Wolfcodes with N separate encoders and a joint decoder. The Slepian-Wolf codes can beselected to ensure a computational complexity to obtain a portion of the input datasequence grows exponentially with respect to a length of the input data sequence unlessall of the N bit streams are compromised. In another embodiment, the input datasequence, X, is compressed using a lossless data compressing techniques; and thecompressed input data sequence is split into N subsequences that are distributed.
