Abstract

Key distribution mechanisms are used to leverage security properties in Wireless Sensor Networks. No key distribution mechanism is coupled to the link security framework TinySec, which considerably sacrifices your security level. The aim of this paper is propose a new approach of key distribution to be used in conjunction with the framework TinySec, solving the weaknesses of this architecture that is based on a very simple scheme: the sharing of the same key before deployment. The combination results in a protocol with a high security level.
