Resumo: |
Key distribution schemes are commonly used to leverage security properties in Wireless Sensor Networks (WSN). No key distribution scheme is coupled to the link layer architecture TinySec, which significantly compromises their security level. The goal of this work is propose a new approach of identity-based key distribution to be used in conjunction with the framework TinySec, solving the weakness of this architecture that is based on a key establishment scheme very simple: the sharing of a same key before the deployment. The identity based key agreement to be use together with TinySec causes the damage from attacks become local and allows that a sensor node send encrypted information to another node the not yet calculated the secret key. The junction results in a protocol with high level of security and is suitable to critical applications of WSN, such as the military or in health. |
