    • A random number generator according to an embodiment of the present invention comprises: a first oscillator generating a first oscillating signal having a first frequency; a second oscillator generating a second oscillating signal having a second frequency different from the first frequency; a sampling unit receiving the first and second oscillating signals, generating at least one entropy source by combining the inputted first and second oscillating signals, and sampling a bit corresponding to the generated entropy source using a third oscillating signal; and a third oscillator and a control unit which control the first and second oscillators and generate the third oscillating signal. The frequency of the third oscillating signal is lower than the first and second frequencies.
    • 根据本发明实施例的随机数发生器包括:产生具有第一频率的第一振荡信号的第一振荡器; 产生具有与第一频率不同的第二频率的第二振荡信号的第二振荡器; 接收第一和第二振荡信号的采样单元,通过组合输入的第一和第二振荡信号产生至少一个熵源,并使用第三振荡信号对与所生成的熵源相对应的比特进行采样; 以及第三振荡器和控制单元,其控制第一和第二振荡器并产生第三振荡信号。 第三振荡信号的频率低于第一和第二频率。
