Even if you make this assumption it still wouldn't be a successful attack because OTP makes no security claims if the key is re-used. If there's no security claim there's nothing to attack to begin with.

No, Dec(0^n) would give you a unique keystream never used before or since. That is the whole point of the >>one-time<< pad.

That's almost correct, but not quite (depending on your definition of correct). It fails to account for the problem that Allen Downey's paper so carefully took care of. I think it's best shown with an image (exaggerated to ha

Oh, I know very well who iq is :) And for a visual demo it might make perfect sense to sacrifice completeness of a solution for speed / code size. But to me, "pick a random number from {k/2^23 : 0 <= k < 2^23, k ∈ ℕ}&qu

What do you mean by "normally distributed values"? Your reply also doesn't follow a normal distribution by the way. Did you mean uniform? For uniform values there is a way to go and my other reply exactly describes how.

You can make this approach very efficient using bitwise operations, and the count trailing zeros instruction common on many CPUs. See my other comment for a reference to the paper describing the technique and a link to a low level implement

Sure, but who said N has to be sizeof(int)? And besides that, the distance between x and successor(x) is not constant throughout the range of [0, 1).

It's a neat trick, but can not generate all floating point values. See my other comment for that.

I don't know about a better book, but I do know how to generate a random float in [0, 1] very efficiently and accurately. A 2007 paper describing the technique is Generating Pseudo-random Floating-Point Value by Allen B. Downey. I have

That's almost the beauty of a lot of audio DSP filters. They can be 1-10 lines of code, but to understand why they work and how to create similar ones with properties you want you need a heavy math background and a 500+ page book (e.g.

This is also why basically all GDPR consent trackers are "accidentally" so forgetful about your choice not to consent. You need to say no every single time (with potentially shifting interfaces). Similarly if I remember correctly
