Secure device-to-device authentication in mobile multi-hop networks

Abstract

In order to deal with drastically increasing mobile traffic these days, device to device connection (D2D) which provides infra-connection’s off-loading is getting a lot of attention. However, we observed that most of the currentD2Dprotocols such as Bluetooth and Wi-FiDirect are not scalable, and vulnerable to main-in-the-middle (MITM) and replay attacks in mobile multi-hop networks. In this paper, we propose novel D2D authentication protocols with a secure initial key establishment using ciphertextpolicy attribute-based encryption(CP-ABE) to solve this problem. By exploiting CP-ABE, the proposed scheme allows the communicating parties to mutually authenticate each other and derive the link key in an expressive and secure way in themulti-hop network environment. According to the analysis results, the proposed scheme is secure against MITM and replay attacks in the D2D mobile multi-hop networks. © Springer International Publishing Switzerland 2014.
