In wireless sensor networks, a sensor node broadcasts its data (such as routing information, beacon messages or meta-data) to all its neighbors, which is called local broadcast. A general case for a sensor node to use a local broadcast is to advertise its routing information. Considering that sensor networks are vulnerable to a variety of attacks and current routing protocols are insecure, a sensor node’s broadcast message should be authenticated by all its neighbors. Unfortunately, the previous work on broadcast authentication in sensor networks mainly concentrates on broadcast messages from a base station which has greater capabilities, not from a sensor node. Those schemes’ properties are not appropriate for broadcast authentication of sensor node’s routing messages. In this paper, we present ARMS, a protocol for broadcast authentication of sensor node’s routing messages. It requires only a small memory space, authenticates routing messages without delay (thus, no buﬀering...
