| Nov 27, 2017 at 9:46 | comment | added | R. Sam | @PaulUszak, As per test results, my entropy source provides ~1 bit/bit entropy, however it fails restart test. Therefore, my HRNG seems prone to Restart Attacks. | |
| Nov 27, 2017 at 9:45 | comment | added | R. Sam | @PaulUszak, I have generated two different datasets for my test. First dataset is the "Continuous Stream of 1,000,000 B" and second is "Restart Dataset". For the generation of Restart Dataset, I have used DevCon Utility to Restart my device. I generate 1000 B, then restart my device using Devcon, then generate 1000 B, so on. Using this method, I generate 1000 files, each of 1000 B with Devcon Restart in between each file. I run " independent and Identically distributed test" on Continuous Stream & Restart Test on Restart Dataset. | |

| Oct 20, 2017 at 13:28 | comment | added | Mike Edward Moras | @PaulUszak Huh? OP writes “The device is certified by ENT test suite, NIST SP800-22, DIE HARDER and TestU01.” (emphasis mine), which covers your tip Run ent and see what that says. As for entropy, OP already got a result of “Minimum Entropy Estimate is 7.88237” This question is about the restart tests OP did after that – which fail, and confuses OP who isn’t sure if that “Minimum Entropy Estimate” is indeed correct or if he's doing the restart testing in a wrong way. | |

| Oct 20, 2017 at 11:22 | comment | added | Paul Uszak | Run ent and see what that says. Nothing has no entropy at all. I don't like any randomness test where you have to configure the type of randomness you're looking for... | |
