IBC-Based Authentication Protocols and a Method of Data Sharing for Cloud Systems

Abstract

In Recent years, the rapid development of cloud computing promotes the technological innovation. In the meantime, the security of cloud attracts many researchers. In this paper, a security architecture is proposed to provide a trust communication mechanism between entities in the cloud. Based on this security architecture and BFIBE, three security protocols are proposed to implement mutual authentication and key agreement, which can resist man-in-middle attacks and masquerading attacks. Besides, based the three protocols, an effective data sharing method is proposed.
