SwiftRNG (100 Mbps) is a general purpose USB device that generates true (hardware) random numbers at a rate of 100 Mbits per second. It can be used in conjunction with SwiftRNG Pro, SwiftRNG Z and SwiftRNG LE.
Devices will be shipped in 1–2 business days. For bulk orders of 10 or more devices, please contact us. Please note that for orders outside of the United States, the buyer is responsible for costs such as duties, taxes, and customs clearance when the shipment is picked up in the destination country.
How it works
SwiftRNG 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 random byte stream. To further reduce the bias, the resulting bytes are hashed as part of a post processing step that produces the final true random bytes. The random bytes are transmitted to the host computer via USB in 16,000 byte packets.
SwiftRNG 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.
‘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 contains patented technology.
