How it works
SwiftRNG Pro utilizes random noise generated from two independent and reliable sources based on the electrical noise produced by an avalanche breakdown effect in zener diodes. The electrical noise generated by each random source is independently amplified, filtered and converted into digital values. The random bytes generated by both noise sources are then combined into the resulting true random byte stream. The final random bytes are transmitted to the host computer via USB in 16,000 byte packets.
Quality checking
SwiftRNG Pro implements an embedded health check test (HCT) that continuously monitors the quality of the random noise sources immediately after the electrical noise is digitized and before any further processing. The HCT logic appends a health check status byte to each transmitted data packet so that the host computer is continuously notified about the health of the generator. In addition, SwiftRNG Pro comes with a new API addition for running internal diagnostics that can be triggered through software or device API.
‘Repetition Count Test’ and ‘Adaptive Proportion Test’ tests are continuously performed through provided SwiftRNG Software API on the host computer to ensure the quality of the final random bytes retrieved through the USB interface.
SwiftRNG Pro contains patented technology.
