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.
