**5. Conclusion and future work**

It is natural that the spread of ubiquitous computing to increase the number of devices with low computing power scattered all over the planet. The security of data transmissions from these devices should be improved in a preventative manner to avoid possible attacks. Regarding WSNs, RSA public key algorithm is the most commonly used is standardized, and achieves efficiency relatively good. The algorithm based on elliptic curves have been extensively studied in academia as an alternative to RSA, and the results show that it is possible to achieve good results with smaller keys. The algorithm MQQ was discovered recently and showed significant results when compared to RSA and ECC, taking as parameters authenticity and digital signature. This algorithm is post-quantum, and may even be a good solution when the quantum computation is standardized. Despite the satisfactory results of MQQ front of RSA and ECC algorithms, there is not a work about performance evaluation specific to encryption and decryption of data.
