Practical Supersingular Isogeny Group Key AgreementKey Agreement • March 27th, 2019
Contract Type FiledMarch 27th, 2019In this section, we present the implementation detail of the supersingular isogeny group key agreement protocol in the case of three parties. The parties compute different large-degree isogenies over different torsion subgroups of a supersingular elliptic curve to efficiently establish a shared secret key. Our software is publicly available4 for evaluation and reproducibility.
