Cracking PRNGsHow do you predict the output of a pseudo random software number generator? 'And fun? If maths is fun, then getting a tooth extraction is fun. A viral infection is fun. Rabies shots are fun.' 'God exists because Mathematics is consistent, and the devil exists because we cannot prove it' 'Who are you to judge everything?' Alokananda #2 20131001 17:51:52
Re: Cracking PRNGsDo you have the generator? In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it. All physicists, and a good many quite respectable mathematicians are contemptuous about proof. #3 20131002 02:56:51
Re: Cracking PRNGsUmm... yeah. But no hint what kind of a generator it is. I am certain that it does not take entropy from the operating system 'And fun? If maths is fun, then getting a tooth extraction is fun. A viral infection is fun. Rabies shots are fun.'

Re: Cracking PRNGsI have seen contrived questions where from the data you can deduce what the generator looks like. But theoretically this is very, very difficult if not impossible. But in practice, poor implementation or bad seeds can make the job somewhat easier. It is known that both Windoze and Lunix have security flaws in their prngs. In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it.

Re: Cracking PRNGsNo, what's that? Last edited by Agnishom (20131002 12:03:38) 'And fun? If maths is fun, then getting a tooth extraction is fun. A viral infection is fun. Rabies shots are fun.'

Re: Cracking PRNGsThe papers probably describe how to. Why do you want to? In mathematics, you don't understand things. You just get used to them.

Re: Cracking PRNGsBecause its fun. Being able to predict things are fun. Last edited by Agnishom (20131003 00:02:24) 'And fun? If maths is fun, then getting a tooth extraction is fun.

Re: Cracking PRNGsHuman prngs? What are those? In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it. All physicists, and a good many quite respectable mathematicians are contemptuous about proof. #9 20131003 00:48:23
Re: Cracking PRNGsBrains. Which get entropy from

Re: Cracking PRNGsEntropies? How do you define that? In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it. All physicists, and a good many quite respectable mathematicians are contemptuous about proof. #11 20131003 00:53:47
Re: Cracking PRNGsHmm 'And fun? If maths is fun, then getting a tooth extraction is fun. A viral infection is fun. Rabies shots are fun.'

Re: Cracking PRNGsSo what are you trying to do here? In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it. All physicists, and a good many quite respectable mathematicians are contemptuous about proof. #13 20131003 01:00:50

Re: Cracking PRNGsAnd when you have done that? In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it. All physicists, and a good many quite respectable mathematicians are contemptuous about proof. #15 20131003 01:04:38
Re: Cracking PRNGsI've not done that. I am willing to do it. 'And fun? If maths is fun, then getting a tooth extraction is fun. A viral infection is fun. Rabies shots are fun.'

Re: Cracking PRNGsThere are two approaches both difficult. A math attack and a debugger. In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it. All physicists, and a good many quite respectable mathematicians are contemptuous about proof. #17 20131003 01:10:09
Re: Cracking PRNGsCan you teach me those or any one of those? 'And fun? If maths is fun, then getting a tooth extraction is fun. A viral infection is fun. Rabies shots are fun.' 'God exists because Mathematics is consistent, and the devil exists because we cannot prove it' 'Who are you to judge everything?' Alokananda #18 20131003 01:13:57
Re: Cracking PRNGsFor the general problem you are asking I do not think so. I was still learning myself. In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it. All physicists, and a good many quite respectable mathematicians are contemptuous about proof. #19 20131003 01:17:37
Re: Cracking PRNGsOk, can you tell how you're learning? 'And fun? If maths is fun, then getting a tooth extraction is fun. A viral infection is fun. Rabies shots are fun.'

Re: Cracking PRNGsKnow what a reverse engineer is? In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it. All physicists, and a good many quite respectable mathematicians are contemptuous about proof. #21 20131003 01:37:37
Re: Cracking PRNGsI've a little idea. 'And fun? If maths is fun, then getting a tooth extraction is fun. A viral infection is fun. Rabies shots are fun.' 'God exists because Mathematics is consistent, and the devil exists because we cannot prove it' 'Who are you to judge everything?' Alokananda #22 20131003 07:29:18
Re: Cracking PRNGsTo you I would say. By the time I am done you will be sleeping. In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it. All physicists, and a good many quite respectable mathematicians are contemptuous about proof. #23 20131003 11:56:56
Re: Cracking PRNGsWhat if we are not allowed to use a debugger? 'And fun? If maths is fun, then getting a tooth extraction is fun. A viral infection is fun. Rabies shots are fun.' 'God exists because Mathematics is consistent, and the devil exists because we cannot prove it' 'Who are you to judge everything?' Alokananda #24 20131003 17:08:54
Re: Cracking PRNGsTo access the prng of the operating system on a foreign machine you would need to cause a buffer overflow error. Of course such a result would qualify as a malicious act.

Re: Cracking PRNGsWhat if it does not belong to the OS? 'And fun? If maths is fun, then getting a tooth extraction is fun. A viral infection is fun. Rabies shots are fun.'
