A novel key agreement protocol based on bilinear pairing

Aim at the problem that current key agreement can not satisfy the security property and the resource-constrained mobile devices, due to its large calculation and communication cost. In this paper, we demonstrate that Yang et al´s scheme is potentially vulnerable to Key-Compromise Impersonation and Forward Secrecy. Afterward, we propose a key agreement protocol using bilinear pairing technique. The analysis of the key agreement shows that proposed scheme satisfies basic security property, with the characteristics of low computational and communication cost.
