Cocoa (WIP)

Trezor for Esp32 with a special emphasis on the generation of random numbers and the statistical detection of non-random patterns.

Statistical tests for random numbers is a series of test to check if a given sequence of bits can be (or not) considered as random.

Test name	Status
Frequency test (monobit)	done
Frequency test within a block	done
Runs test	done
Longest run of ones	done
Matrix rank test	done
Discrete Fourier Transform (Spectral)	done
Non-overlapping Template Matching	done
Overlapping Template Matching	WIP
Maurer’s “Universal Statistical”	-
Linear Complexity	-
Serial	-
Approximate Entropy	-
Cumulative Sums (Cusum)	-
Random Excursions Variant	-
