Abstract :
By means of this study We have optimized the performance of the cryptographic algorithm Rijndael in a low cost hardware/software system, in a FPGA Spartan3e board of Xilinx with a MicroBlaze soft-processor. After the study of its execution in six systems with different configurations, the hardware bits rotation of MicroBlaze´s optimizes the process of coding and deciphered, and the combination with the implementation of a coprocesador with a Galois field multiplier optimizes the key expansion.
