Abstract (in Japanese) (See Japanese page) 
(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 8.33 Mbps throughput.
