Abstract - True random number generators (TRNGs) are widely used in cryptographic applications such as key generation, random padding bits, and generation of challenges and nonces in authentication protocol. This paper proposes a new and efficient method to generate true random numbers in XILINX by utilizing the random jitter of free running oscillators as a source of randomness.The main advantage of the proposed true random number generator utilizing programmable delay lines is to reduce correlation between several equal length oscillator rings, and thus improve the randomness qualities. Generalised FIFO is used to store generated sequence of patterns.clock gating architecture to limit the switching activity of the address decoder which improves the power efficiency of the proposed number generator. element structure is adapted to evaluate the clock cycle to the present ring counter block and to release the clock pulse to the next ring counter block.

Key Words:  TRNGs, field programmable gate array (FPGA), ring oscillators
