  • A true random number generator: TrueRNG v3

    ,

    In this work we’ll consider a particular true random number generator (TRNG): TrueRNG v3. This device is developed by the company ubld.it, manufacturers of some cool electronics. The TrueRNG Hardware Random Number Generator uses the avalanche effect in a semiconductor junction to generate true random numbers. The avalanche effect has long been used for generation of random…

  • Pseudorandomness, quasirandomness, and true randomness

    ,

    When people talk about randomness in quantitative development, they usually mean pseudorandomness. Pseudorandom refers to a sequence of numbers or data that appears random but is actually generated by a deterministic, predictable mathematical algorithm making it repeatable if you know the starting point (the seed). In many financial applications this predictability does not matter. For…

  • How to learn cryptography

    The understanding of cryptocurrencies and Blockchain implies at least a cursory familiarity with cryptography. In this short note we will consider some of the tools that you could use to learn cryptography rapidly. Prof. Ross Anderson‘s book Security Engineering: A Guide to Building Dependable Distributed Systems is now in its third edition. The scope of this book…
