RESUMO
There is a variety of application scenarios in wireless sensor networks such as medical monitoring, military, home and office security, agriculture and so on. These applications deal with Wireless Sensor Networks (WSNs) odd particularities such as limited power and computational capacities, hardware heterogeneity, low bandwidth, dynamic topology and scalability issues. Due to their inherently distributed nature WSN 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. The main goal securing WSNs is to ensure integrity, authenticity and confidentiality of data whilst maximizing network lifetime. In this scenario we introduce SM-Sens, a secure middleware that helps the development of high-level application whilst hiding WSN managing complexity and security mechanisms. Our middleware uses symmetric and public-key cryptography, message authentication and a role-based key distribution mechanism. The middleware defenses are efficient against a number of attacks (selctive forwarding, black hole, sybil and so on) either preventing from them or minimizing the damage they may cause to the network.
