The output of a good block cipher in feedback mode will pass Diehard tests, though it is not crypto-secure.
I often see the phrase 'pass Diehard test' though I don't see from the documents of Diehard how to evaluate the volumenous printout of Diehard to say exactly whether the test is passed or not. Furthermore the component asc2bin.exe of Diehard is buggy.
My rough understanding: the 'P' value is a measure on the hypothesis that the test sample is a truly random sample, where truly random is defined by the expected statistical properties being measured. Eg in 100 bits you expect to find 50 1's; if you count 48, is your 100-bit sample consistant with it being unpredictable?
My concrete problem is: With the bunch of p-values how does one (in accordance with the intention of the designer of the package) go about to determine that the test is passed at a certain confidence level. I don't see anything in the documents instructing the user to do this. Maybe I indeed missed something. Please point that out in this case. M. K. Shen
