The quantum process that these guys exploit is the way light sources emit photons. Because each emission is a quantum process, the instant of emission cannot be predicted. So the number of photons that a light source emits in a unit of time will always vary by an amount that is entirely random.




각종 양자난수생성 방법들 중에 제일 특이한 듯 ㅋㅋ 값싼 방법을 찾다가 발견한 방법인데, 마침 스마트폰에서 보안을 위해 난수를 생성해야할 일이 많은 편이라 여러모로 딱이라고 함 ㅋㅋ
