Abstract

Wireless Sensor Networks (WSNs) are exposed to numerous security threats that can affect the execution of applications. Securing WSNs is challenging due to their unique nature as an application and a network, and due to their limited capabilities. Therefore we introduce SM-Sens, a secure middleware that helps bridge the gap between high-level application requirements and WSN managing complexity. Our middleware uses defense mechanisms like asymmetric cryptography and authentication. The middleware defenses are efficient against a number of attacks either preventing from them or minimizing the damage they may cause to the network. We evaluate our middleware through extensive analysis, implementation, simulations and measurements. We argue that SM-Sens is viable and attractive to applications with security requirements.
