Converting random bits into random numbers

Abstract

Converting random bits into random numbers is necessary for cryptographic protocols such as key agreements, public key encryptions, digital signatures and so on. In this paper, we propose the simple partial discard method and the complex partial discard method that convert random bits into random numbers. They are up to two times more efficient than standardized techniques.

Notes

  1. 1.

    We developed the SPDM and the CDPM before Lumbroso published the FDR on arXiv.

  2. 2.

    The reference code given in [7] is not optimal. Thus we optimized it.
