This paper introduces a method of generating true random numbers using only digital logic. It shows that asynchronous sampling the output of ring oscillators can be used as a source of random numbers in digital hardware and that Linear Hybrid Cellular Automata can be used as scramblers to substantially improve the quality of the random data. A highly efficient and scalable FPGA implementation of the proposed circuit has been tested in hardware and shown to generate 32-bit true random numbers at rates over 16Gbps. The generated random numbers have been tested with the DieHard test suite and passed all 15 randomness tests.
