Table 2 The result of compressing a 1.41 Mbit/s bitstream with differently sized Toeplitz extractors \(\mathcal{T}\) with compression ratios CR. The bistream was generated using protocol 2 with \(L=6\) and with the first LSB bit removed, which gives a biased output with correlations present on the order of L bits. The min-entropy per bit was determined after extraction by splitting the bitstream in 10 equally sized samples of approximately 106 bits and then using either non-IID or IID tests, depending on whether the IID assumption holds for the given bitstream
