|The statistical tests on Rabbit were performed using the NIST Test Suite [17], |the DIEHARD battery of tests [14] and the ENT test [22]. |Tests were performed on the internal state as well as on the extracted o utput. |Furthermore, we also conducted various statistical tests on the key setu p function. |Finally, we performed the same tests on a version of Rabbit where each s tate variable |and counter variable was reduced to 8 bit. |No weaknesses were found in any of these cases.

|This package will address the problem of evaluating (P)RNGs for randomne ss. |It will be useful in: |o identifying (P)RNGs which produce weak (or patterned) binary sequences , |o designing new (P)RNGs, |o verifying that the implementations of (P)RNGs are correct, |o studying (P)RNGs described in standards, and |o investigating the degree of randomness by currently used (P)RNGs.
Ich hab vor einiger Zeit mal mit den DIEHARD Tests rumgespielt. Die
Vielleicht sind ja die NIST Tests besser.

Executables sind auf keinen Fall random. Das ist auch gar nicht vorstellbar! Die Suite zeigte stets 14 von 15 Tests als Totalversagen an (igamc: UNDER FLOW). Nur 'LinearComplexity' wurde stets bestanden.
|4 Analysis of Cipher |4.1 Statistical Tests |Statistical tests provided by the CRYPT-X [8] package were performed |on keystream produced by the Dragon cipher. |The frequency, binary derivative, change point, subblock and runs tests |were executed with 30 streams of Dragon output, each eight megabits in l ength. |The sequence and linear complexity tests were executed for the 30 stream s |with two hundred kilobits each. |Dragon passed all pertinent statistical tests.

Die dieharder-Tests "beweisen" das aber. Zumindest deinem Sprachgebrauch von "beweisen" zufolge.

Wie denn auch, wenn ich eine Testsuite verwende?
h von "beweisen" zufolge.
Das ist irrelevant.
Wenn Software dies feststellt, ist da etwas faul.
Ich befasse mich aber nicht mit dieharder. Weil NIST eine Neufassung seiner Testsuite plant.
Das ist bewiesen. Deine Meinung ist irrelevant. Beweise stehen nicht unter dem Vorbehalt der Meinung eines Schellong.
