Authenticated key agreement protocol based on hierarchical identity Cao Chenlei Liu Mingxi Zhang Ju Yang Yixian The current Identity-based Authentication Key agreement protocol is a trusted third party with a single private key generator (PKG), but it is difficult to meet the requirement of identity layering registration and authentication. This paper reconstructs the constituent elements of the private key based on the hierarchical Identity Encryption (Hibe) system. A authenticated key agreement protocol based on hierarchical identity is proposed by using bilinear mapping on elliptic curve multiplication cyclic group, which provides a secure session key bargaining machine for cloud entities belonging to different levels.
