Hyang-Sook Lee, Young-Ran Lee, Juhee Lee · Communications of the Korean Mathematical Society · 2003
In this paper, we propose multiparty key agreement protocols by generalizing the Blom's scheme based on 2 variable polynomials. Especially we develop three party and four party key agreement schemes with security. The advantage of the new schemes is to have small demands on storage space.
