2021-01-21 11:50:33 +0100 | asked a question | Which hash function can be used to get $w=H(d)\in F^n$ case? I am trying to implement a cryptographic scheme. For a arbitrary message $d$ , I need a Hash Function $\mathbb{H}$ that can compute the hash value $w=\mathbb{H}(d)\in \mathbb{F}^n$. Here $F$ is a finite field of order four. I can not find any hash function which outputs field values. Can someone please help and show me the right direction? |

2021-01-19 10:36:55 +0100 | asked a question | Multiply polynomials from different rings Suppose I take a polynomial from $K[x]$, say $x^2 + 5x$, and another polynomial from $K[y]$, say $y^3$. I want to formally multiply them and get $x^2y^3 + 5xy^3$ as the output. How can I do that? Note: My efforts: When I do |

one can ask for a random element using the The random polynomial I obtained that way was of degree two: If I only want a random linear polynomial from this ring, how can I get one? |
