Attribute-based handshake protocol for mobile healthcare social networks

In this paper, we study the privacy protection problem of handshake protocol for mobile healthcare social network, and introduce the concept of attribute-based handshake (ABH) protocol. Using ABH, users in mobile healthcare social network can make a handshake to authenticate each other and obtain a common session key without exposing their privacy when their attributes meet the social needs of each other. Then, we provide the formal definition and security model of ABH protocol with a specific construction proving its security in the standard model. Finally, we introduce how to deploy our ABH protocol in the mobile healthcare social network.
