Why does this never verify? It's mostly equations and it seems like they're pretty much all equalities. Am I relying too heavily on the modulus axioms ...
Say I have a circular list which would look like this to a human: How can I determine whether two indices are adjacent please? So far I have: D ...
How to get primes p and q from g^p mod n, g^q mod n, and g^n mod n where n=p*q. G is unknown and can be any value. ...
I am implementing RSA digital signature algorithm and one of the operations needed is modular exponentiation of 2048 bit strings. and the hardware i a ...
I'm trying to implement finite field arithmetic to use it in Elliptic Curve calculations. Since all that's ever used are arithmetic operations that co ...
Here is a conjecture: For expression a op b where a and b are of the same unsigned integral type U, and op is one of the compound assignment operator ...
I'm trying to write a function, rotateByX, that accepts two parameters, a 4x4 matrix and a number that represents the degrees to rotate the matrix. Th ...
I am currently reading about the Rabin Karp algorithm and as part of that I need to understand string polynomial hashing. From what I understand, the ...
Can anyone please explain why this happens ?? : Also when we write the similar for 'short' , the compiler takes the product as integer type despite ...
I would like to check if there is an easy way to implement a check of linear (in)dependence of vectors but using modular arithmetic mod 2. For exampl ...
I'd like to prove the following lemma: but am finding it surprisingly tricky. The lemma feels straightforward; it just says that in order to prove ...
I have an array of n positive integers. I want to calculate a list of all contiguous subarray products of size k modulo p. For instance for the follow ...
below is the code for modular expone ntiation with two different approaches. in below code expo1() function is the optimal or correct method and exp ...
This question was migrated from Cryptography Stack Exchange because it can be ...
I am trying to transform a formula over to a finite-field equivalent of that formula. The formula can be seen below: Now I have this implemented an ...
I am trying to write an algorithm for the Change-making problem. I am assuming the coin system is canonical, which means the greedy algorithm of alwa ...
pow accepts a third argument for modulo pow(x, y, z) that is more efficient computation than x ** y % z. How can you do that with arrays? What I've tr ...
The bottleneck of my code is the repeated calling of pow(base,exponent,modulus) for very large integers (numpy does not support such large integers, a ...
this is so far all i have done i am trying to optimize the code for less time.but it is not working. another approach I tried: if i < j <= n ...
