Security in Sensor Networks. By : Rohin Sethi Aranika Mahajan Twisha Patel. Outline. Introduction Time Syncronization Attacks Denial of Service (DoS) Attacks Conclusion. Need for Security in Sensor Networks. Broadcast nature of Wireless Communication Lack of tamper-resistant hardware
provide a mechanism for synchronizing the local clocks of the nodes in a sensor network
used by many applications of sensor networks, such as tracking and localization.
Attacks on time-synchronization protocols:
have one main goal, to somehow convince some nodes that their neighbors’ clocks are at a different time than they actually are.Time Synchronization Protocols
