tRNG

To generate random number for QKD, we use SwiftRNG Pro from TectroLabs. Documentation for device is available on website of TectroLabs.

Picture below show you the path of random bytes. We have a small API sends "x" command to SwiftRNG Pro, the device returns 16000 bytes of random data. Then data is sent through PCIe to FPGA using axistream protocol, jesd_transport.v manages to read data from axistream fifo fifo_128x16

rng data flow

On Alice, we're going to use the second tRNG device to generate the signal for the second AM. Data flow is the same as above but the destination is module decoy.v
