| Resumo: | Wireless sensors and actuators Networks specified by IEEE 802.15.4, are
becoming increasingly being applied to instrumentation, as in instrumentation of oil
wells with completion Plunger Lift type. Due to specific characteristics of the
environment being installed, it s find the risk of compromising network security, and
presenting several attack scenarios and the potential damage from them.
It`s found the need for a more detailed security study of these networks, which calls
for use of encryption algorithms, like AES-128 bits and RC6. So then it was implement
the algorithms RC6 and AES-128, in an 8 bits microcontroller, and study its
performance characteristics, critical for embedded applications. From these results it
was developed a Hybrid Algorithm Cryptographic, ACH, which showed intermediate
characteristics between the AES and RC6, more appropriate for use in applications
with limitations of power consumption and memory. Also was present a comparative
study of quality of security among the three algorithms, proving ACH cryptographic
capability. |
