“…"The sender uses the public key of the receiver to encrypt open text in ciphertext and after receiving the resulting ciphertext the receiver uses its private key to decrypt the ciphertext, again retrieving readable text" [17]. In its model it is easy to determine the flow of the encryption and decryption process according to the key creation steps, where encryption occurs, but only the encryption with the key pair (private, public) can be decrypted.…”

The encryption approach is widely used in mobile applications where there is message exchange and in banking transactions or financial pointers tools. The present research has as a proposal to approach an algorithm developed in C language and based on the RSA encryption methodology using the symmetric and asymmetric key concepts in order to demonstrate its use in the exchange of messages where there is secrecy of information, thus the importance of information security, its use has obtained interesting results with the manipulation of large scale vectors where the number of characters is a factor the process of letter inversion for encryption and decryption.

“…Studies by [34], [35] and [36] showed that codes based on the MIRACL offers better performance than codes based on other cryptographic libraries such as Crypto++, LibTomCrypt, OpenSSL and Lydia+GMP . Regarding MQQ algorithm, was used the version written by [26] in his dissertation.…”

Embedded devices are present in many of our daily activities. In some of these activities is necessary to protect the data from possible attacks. Due to resource constraints, it is necessary to study security techniques that consume the least possible resources of embedded platforms. This paper presents the performance evaluation of asymmetric cryptographic algorithms in embedded systems with Advanced RISC Machine (ARM) processor. The algorithms studied were Rivest-Shamir-Adleman (RSA), Elliptic Curve Cryptography (ECC) and Multivariate Quadratic Quasigroup (MQQ). We have used three criteria in our comparison: the processing time, memory and processor usage. We used the SimpleScalar tool for our simulations analysis. The results showed that MQQ is a good algorithm for embedded systems since it is better than ECC and RSA.

Este trabalho avalia o comportamento mecânico do concreto asfáltico embebido em grafite natural (CA-GRAFP) de um aparelho de flexão de 4 pontos. Os modelos experimentais apresentaram frequências de 0,1 Hz, 0,2 Hz, 0,5 Hz, 1 Hz, 2 Hz, 5 Hz, 10 Hz e 20 Hz e temperaturas de 0 ° C a 40 ° C em incrementos de 5 ° C conforme EN 12697 -26. O objetivo foi avaliar o uso de grafite natural na substituição de uma carga tradicional, bem como avaliar as propriedades relacionadas à rigidez resultante de inúmeras combinações de carga. Os resultados mostraram que as amostras de concreto asfáltico embebido em grafite (CA-GRAFP) tiveram um aumento no seu módulo elástico quando comparado ao concreto asfáltico de referência (CA-REF) à medida que a frequência e a temperatura aumentaram.
