Keyed hash function from large girth expander graphs
Eustrat Zhupa, Monika K. Polak
In this paper we present an algorithm to compute keyed hash function (message authentication code MAC). Our approach uses a family of expander graphs of large girth denoted $D(n,q)…

On hyperelliptic curves of genus 3
Lubjana Beshaj, Monika Polak
We study the moduli space of genus 3 hyperelliptic curves via the weighted projective space of binary octavics. This enables us to create a database of all genus 3 hyperelliptic cu…

Graph based linear error correcting codes
Monika Polak, Eustrat Zhupa
In this article we present a construction of error correcting codes, that have representation as very sparse matrices and belong to the class of Low Density Parity Check Codes. LDP…
