Center node: "strong secrecy for erasure wiretap channels"
  Abstract: We show that duals of certain low-density parity-check (LDPC) codes, when used in a standard coset coding scheme, provide strong secrecy over the binary erasure wiretap channel (BEWC). This result hinges on a stopping set analysis of ensembles of LDPC codes with block length n and girth ⋛ for some ⋛. We show that if the minimum left degree of the ensemble is l min , the expected probability of block error is O(1/n⌈l mink/2⌉ −k) when the erasure probability ∊  ef , where ∊ ef  depends on the degree distribution of the ensemble. As long as l min  and k > 2, the dual of this LDPC code provides strong secrecy over a BEWC of erasure probability greater than 1–∊ ef .
