Fast True Random Bit Generation With an SOA-Based Random Fiber Laser

Physical random bits are generated at rates up to 40 Gbps using an 8-bits digital oscilloscope acquiring the optical intensity at the output of an SOA-based random fiber laser. The simple and minimal off-line post-processing (the selection of 4 LBS) can be easily implemented in real time. The true random bits sequences passed all NIST tests.

Automated summary

Physical random bits are generated at rates up to 40 Gbps by acquiring the optical intensity from an SOA-based random fiber laser using an 8-bit digital oscilloscope. The post-processing involves selecting 4 least significant bits and can be easily implemented in real time. The generated random bits pass all NIST tests.
