DoS attack-tolerant TESLA-based broadcast authentication protocol in Internet of Things

The Internet of Things (IoTs) is an emerging concept referring to networked everyday objects that interconnect to each other via wireless sensors attached to them. TESLA is a source authentication protocol for the broadcast network. Scalability of TESLA is limited by distribution of its unicast-based initial parameter. Low energy consumption version of TESLA is μTESLA, which is designed for wireless sensor network (WSN), while cannot tolerate DoS attack. TESLA++ is the DoS-tolerant version and is designed for VANET. TESLA++ cannot be accepted by WSN because of its higher consumption of power. To realize secure and robust DoS attack in the hybrid-vehicle-sensor network, we provide a TESLA-based protocol against DoS attack with a lower consumption of power. Analysis results demonstrate that using our protocol is better than using μTESLA or TELSA++, respectively.
