Abstract

In Wireless Sensor Networks, key management is required to offer a secure communication between sensor nodes. Many key management mechanisms have been proposed while considering the characteristics of sensor nodes. Despite the advances of key management techniques, wireless sensor networks still have vulnerable point since sensor nodes have the communication restrictions such as an ultralight, a low power and a short distance. Therefore an adversary can compromise easily a few sensor nodes and may obtain keys between noncompromised nodes. By using obtained keys, the adversary can insert forged or modified messages. The abused key by adversary is called "misused key". In wireless sensor network, the misused key can cause mortal consequences to user. This paper introduces a misused key detection mechanism of Liu and Dong and proposes efficient and secure misused key detection mechanism in wireless sensor networks. Additionally, in our simulation result, the energy consumption of our scheme is 20% more efficient than that of the Liu and Dong's scheme on the average.
