New Lattice-Based Broadcast Authentication Protocol for Wireless Sensor Networks

Abstract

At present, wireless sensor networks have become one of the indispensable infrastructures in people’s lives. Considering the frequent mobility of wireless sensor network nodes, an efficient lattice-based random broadcast authentication protocol is proposed. The security of the proposed protocol is based on the SIS problem which helps to resist against quantum attacks. In this paper, we propose two forms of broadcast authentication, that is, one-to-many broadcast authentication and one-to-one broadcast authentication. The proposed protocol satisfies the broadcast authentication property. Moreover, the resistance against man in the middle attack, antireplay attack, unforgeability, and scalability properties are achieved. Moreover, its efficiency has certain advantages with other lattice-based studies.
