A New Design of Asymmetric Group Key Agreement Protocol without any Third Party Controller

Shruti Nathani, B.P. Tripathi


Recently in 2016, to authenticate the group members Li et al. uses the identity based public key cryptography in their proposed authenticated and dynamic round optimal asymmetric group key agreement protocol(ADASGKA). Inspire from this ADASGKA protocol in this paper we propose a new identity based authenticated and dynamic asymmetric group protocol using bilinear pairing without any extra third party controller. Our security analysis shows that the proposed protocol can resist all the required attacks and satisfies the desirable security attributes.
