Practical Non-Interactive Key Distribution Based on Pairings

Régis Dupont and Andreas Enge

Abstract: We propose a practical non-interactive key distribution protocol based on pairings and define a notion of security for such a scheme. We prove the security of the system in this setting under the GDBH assumption, and present some possible realisations using Weil or Tate pairings on supersingular and ordinary elliptic curves.
