我们表明，极化码渐近实现窃听信道的整个容量模糊区域时，窃听器的信道相对于主信道退化，并使用弱保密的概念。我们的编码方案也实现了物理退化的接收机正交中继信道的容量。我们展示了中等块长度的二进制擦除窃听信道的仿真结果，比较极化码和两个边缘类型的LDPC码。
We show that polar codes asymptotically achieve the whole capacity-equivocation region for the wiretap channel when the wiretapper's channel is degraded with respect to the main channel, and the weak secrecy notion is used. Our coding scheme also achieves the capacity of the physically degraded receiver-orthogonal relay channel. We show simulation results for moderate block length for the binary erasure wiretap channel, comparing polar codes and two edge type LDPC codes.
