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.
