On the Design of LIL Tests for (Pseudo) Random Generators and Some Experimental Results [PDF]
, 2014 NIST SP800-22 (2010) proposes the state of art testing suite for (pseudo) random generators to detect deviations of a binary sequence from randomness. On the one hand, as a counter example to NIST SP800-22 test suite, it is easy to construct functions ...
