The algorithm is very nice. But I think you should think about what it means to divide one integer by another. The quotient of that operation is an integer. The remainder is an integer. Can you express the number in terms of the quotient an

Finding divisors is often hard when your number is large. It turns out the condition that a number n can be expressed as a multiple of two other numbers is equivalent to there being a number z less than n except for 1 and n-1 so that (z^2 m

Is he though? He publishes frequently in a bunch of journals that I've never heard of but an actual cryptography expert would know that it is the asymptotic behaviour of an algorithm that matters. You could write exactly the same post

This is a recent development. Apple only started to care about iOS security around 2012 for example.

Quantum computing is an area where the hype is out of proportion to the certainty about time until its feasible. With self driving cars there are arguments about the number of decades until it is in use. With QC the uncertainty about buildi

"Define a function h such that h(f(x), f(y)) is true iff x = y" If an attacker can compute such a function then any cryptosystem would be broken because of the attack you give. The Goldwasser,Micali paper "Probabalistic Encry

Good mathematical work is rarely an all or nothing proposition. Many independent ideas are required and when the mathematician is very good it is rare that there will be many mistakes. So even if there are issues with some aspect of the pro

First, the demonstration Kahneman arranged is simply a demonstration of regression to the mean and is not evidence of the validity of his hypothesis. Is the hypothesis itself wrong? We can test the validity of the hypothesis on all people b

Where did you get nobility from. This isn't the author's point at all. Obviously knowledge about different areas of knowledge can be of more practical benefit at different times. The point is that in the next few years knowledge o
