Claim 12:
13. A method for testing a bit sequence generated by a Random Number Generator, wherein the method comprises applying one or more statistical tests to the bit sequence, in response the detection of N bits generated by the Random number generator, each statistical test being configured to test randomness in said N bits generated by the Random number generator (11), each statistical test providing at least one test parameter from the bits of said sequence, the testing method comprising:
comparing at least one test parameter related to each statistical test to a threshold;
determining if said bit sequence is valid depending on the comparison made for said each statistical test;
wherein said at least one test parameter is a parameter related to the statistical test and determined from N and from a target error probability,
wherein the test parameter is the integer part of the length of a run.
