| Abstract: | A design of TRNG based on Galois ring oscillator is proposed in this paper. To improve the randomness, the proper harvesting mechanism and post-processing are employed. Because only using digital circuit, this design has low power consumption, high integration and is easy to be realized. The TRNG realized is evaluated with AIS31 which is the criterion of the TRNG, the result of the experiment indicates that this design meets with the requirements of AIS31. |
