One of the AVX-512 instruction set extensions is AVX-512 + GFNI, " Galois Field New Instructions". Galois theory is about field extensions. What does that have to do with processing vectorized int...

I want to use python interpolate polynomial on points from a finite-field and get a polynomial with coefficients in that field. Currently I'm trying to use SymPy and specifically interpolate (from...

I am trying to implement a Reed-Solomon encoder-decoder in Python supporting the decoding of both erasures and errors, and that's driving me crazy. The implementation currently supports decoding o...

I am puting up a C code for the Multiplication of block (Alogrithm 1) in the GCM SP-800-38D document here. Page 11-12. Having completed the code, I want to see if there are any way I can test the ...

These 2 functions perform Extended Euclidean Algorithm, and then find the multiplicative inverse. The order seems right, but it's not coming back with what I'm expecting as per this tool from U of ...

I am trying to understand how the galois LFSR code works. On the wikipedia page there is a figure with an example. There is a C snippet code. #include <stdint.h> uint16_t lfsr = 0xACE1u; uns...

I am attempting to generate QR codes on an extremely limited embedded platform. Everything in the specification seems fairly straightforward except for generating the error correction codewords. I ...
