Abstract
Randomness in Bell test data can be device-independently certified by Bell's theorem without placing assumptions about the experimental devices. The device-independent randomness has very demanding requirements about the experimental devices and relatively lower output randomness. With the same Bell test data we can extract substantially more randomness without using Bell's theorem. To achieve this goal, we introduce a remote-state-preparation dimension witness and a semi-device-independent randomness certification model which is based on it. This is one important step towards practical use of the Bell test in randomness generation.
