Shannon entropy is one of the widely used randomness mea-sures especially for cryptographic applications. However, the conventionalentropy tests are less sensitive to the inter-bit dependency in random sam-ples. In this paper, we propose new online randomness test schemes fortrue random number generators (TRNGs) based on the mutual infor-mation between consecutive k-bit output blocks for testing of inter-bitdependency in random samples. By estimating the block entropies ofdistinct lengths at the same time, it is possible to measure the mutualinformation, which is closely related to the amount of the statistical de-pendency between two consecutive data blocks. In addition, we proposea new estimation method for entropies, which accumulates intermediatevalues of the number of frequencies. The proposed method can estimateentropy with less samples than Maurer-Coron type entropy test can. Bynumerical simulations, it is shown that the new proposed scheme can beused as a reliable online entropy estimator for TRNGs used by crypto-graphic modules.
