3 ate The results survey presented by the authors show some different level of what it concerned testing statistic of the RNG implementation from theories to practical results. Where the tests standard evaluate and updated to covert more the characteristic of the RNG starting by the simple to a complex and hard batteries of test. We can analysis the result by two category that it seen more stable and trust tests as the NIST and TESTU01, where the other batteries are even for old tests or they are included in thous two batteries.
5 \textit{NIST} is a practically the first batteries that included all mathematical and physical properties to test the RNG and content a 15 tests ....
6 the analysis show that no all papers give a details about this section of tests, where there is some difficult to say it pass it or now specially the coverege of tests.
7 What has been notice that almost all works try to pass to NIST batterie where just 10 works pass the tests almost of them are using chaotic methodes and few of LFSR and CA PRNG also pass the test. this analysis show us that even the PRNG methodes can be implemented on FPGA bu few of them try to pass the NIST test. However, almost all TRNG reviwed can pass the tests some TRNG cal allso pass the AIS batterie.
