In this work is proposed a comparative study of cryptographic algorithms to be applied in Wireless Sensor Networks. Having as motivation the lack of researches with practical results, the main goal of this work is to verify the viability of the insertion of studied algorithms in a real environment based on a Software-Defined Radio system. Due to the internal limitations of each node, efficiency is an aspect as important as cryptographic quality, in order to ensure a good performance of the security technique. For this, it will be analyzed data such as execution time, memory usage, processing cost and power consumption. Thereby, it is expected to increase the security in Wireless Sensor Networks, having in consideration its performance, memory and energy constraints.
