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.
