摘要：

In this work, we have studied the possibility of using a MEMS accelerometer to generate seeds for a secure cryptosystem. The noise signal generated by the accelerometer at rest has been studied and, after a post-processing process, has been used to generate the initial parameters of a stream cipher based on a piecewise linear chaotic map. The encryption algorithm has been implemented in a Xilinx Virtex 7 FPGA achieving a throughput of 200 Mbps using 390 LUTS. The resulting sequences generated by this system have been subjected to the NIST randomness tests, passing all of them, indicating that the whole encryption system is secure.
