Table 1 Comparison of SP800-90B testing for protocols 1 and 2 (no extraction). From protocol 1 we see that the non-IID entropy is underestimated if the IID assumption is true. On the contrary, we can see from protocol 2 that the min-entropy is greatly overestimated in IID testing if the IID claim is false; non-IID testing has to be done to get an accurate min-entropy initial claim before extraction. Protocol 1 entropy is estimated from one sample of size \(0.4 \times 10^{6}\) bits, where for protocol 2, 10 samples of \(1.4 \times 10^{6}\) bits were used
