Wireless sensor networks (WSNs) provide a technological basis for many different security critical applications such as critical infrastructure monitoring, healthcare and battlefield. However, WSNs are often deployed in unattended, harsh and hostile environment that makes them susceptible to many security threats and are specifically prone to physical node capture in which the adversary can easily launch the so-called insider attacks such as node compromise, bypassing the traditional security mechanisms based on cryptography primitives. So, the compromised nodes can be modified to misbehave and disrupt the entire network and can successfully perform the authentication process with their neighbors, which have no way to distinguish fraudulent nodes from trustworthy ones. Trust and reputation systems have been recently suggested as a powerful tool and an attractive complement to cryptography-based schemes in securing WSNs. They provide ability to detect and isolate both faulty and malicious nodes. Considerable research has been done on modeling and managing trust and reputation. In this talk, we present trust topic issue that remains an open and challenging field.
