AMD to fix buggy RNG endangering cryptographic security : Local privileges required to exploit flaw in Ryzen and Epyc CPUs. Some patches available, more on the way

Generating truly random numbers is both hard and a bit of a catch-22. Random number generators need to be reproducible to ensure they work but also able to generate a random number no one can guess. Ensuring the seed is random is the key and hard to do securely.

記事にもありますが、プログラミング言語に搭載されている乱数は疑似乱数で、似たような乱数が繰り返される周期性をもつのが弱点です。
ただ、モダンな言語に実装されているメルセンヌ・ツイスタは周期が非常に長く(10のあとに0が6000個つくだけの回数)、それでいて計算量が少ない(応答が速い)ので、ゲームを始めとする多くの分野で使われています。 www.pahoo.org/e-soul/webtech/php01/php...

補足:乱数(PHPでパスワードを生成) ここで、組み込みの乱数関数について補足しておく。 デジタル・コンピュータは、計算機としては同じ引き数を渡したら常に同じ戻り値を返すことができる。だが、このことから、原理的に一様乱数を発生することができない。 そこで、コンピュータでも一様乱数に近い疑似乱数を“計算”できるアルゴリズムが研究されており、なかでもサンプル・プログラムで使用した組み込み関数  mt_rand  が採用しているメルセンヌ・ツイスタは、少ない計算量で疑似乱数を発生することが証明されている。

お正月ば双六――

プログラムでサイコロを振るとき、それが一様乱数ではないことに留意されたい。

たとえばPythonには、random.randint, numpy.random.default_rng, secrets.randbelow, os.urandomといった乱数があるが、一様分布から1%以下の確率で偏っている。 www.pahoo.org/e-soul/webtech/php01/php...
