| Abstract(in English) | Metastability of RS latch is utilizable as an entropy source for true random number generators (TRNG). This kind of TRNG is comprised of logic gates, which can be integrated into a logic LSI. Though latch-based TRNG has been mostly implemented with full-custom LSI technology, this study presents an implementation with common FPGA technology. The RS latch in our TRNG is implemented as a hard-macro to guarantee the quality of randomness, minimizing the clock skew and load imbalance of internal nodes. The quality and throughput are further improved by XOR'ing the output of 32-128 latches. The derived design was implemented with Xilinx Virtex4 FPGA (XC4VFX20), and passed NIST test without post-processing. A TRNG of 128 latches occupies 290 slices, while achieving 8.33Mbps throughput. |
