An Asynchronous Node Replication Attack in Wireless Sensor Networks
نویسندگان
چکیده
Applications of wireless sensor network (WSN) are growing significantly, and many security protocols meant for WSN have been proposed. One of the unique problems of WSN is that the sensor nodes are not tamper resistant as the main attraction of deploying WSN is its low cost. Node replication attack exploits this weakness to launch an attack, in which cryptographic secrets from the compromised sensor nodes are used to create duplicate sensor nodes in large number. Then these sensor nodes are placed in critical locations of the WSN to mount attacks. Several protocols were proposed to defend WSN against the replication attack, and one of the promising among them is distributed detection protocol presented by Parno et al. at IEEE S&P 2005. However, we show in this paper that their distributed detection protocol is vulnerable to an asynchronous node replication attack. Further, we modify the protocol to make it secure for dynamic WSN supporting node mobility.

Sybil attacks pose a serious threat for Wireless Sensor Networks (WSN) security. They can create problems in routing, voting schemes, decision making, distributed storage and sensor re-programming. In a Sybil attack, the attacker masquerades as multiple sensor identities that are actually controlled by one or a few existing attacker nodes. Sybil identities are fabricated out of stolen keys, obt...
متن کاملUnauthenticated event detection in wireless sensor networks using sensors co-coverage
Wireless Sensor Networks (WSNs) offer inherent packet redundancy since each point within the network area is covered by more than one sensor node. This phenomenon, which is known as sensors co-coverage, is used in this paper to detect unauthenticated events. Unauthenticated event broadcasting in a WSN imposes network congestion, worsens the packet loss rate, and increases the network energy con...
