WebJul 19, 2016 · What are you using the generator for - why do you need randomness? Note that "true" randomness is generally actually useless (since it's not repeatable), hence seeding a pseudo random generator like you're doing, but both how you generate the seed and how you generate the "next" number are extremely important. Note that, very … WebCSPRNGの要件は、2つのグループに分類されます。 まず、統計的ランダム性テストに合格します。 第2に、たとえ初期状態または実行状態の一部が攻撃者に利用可能になっ …

WebIf we define a CSPRNG as something that generates output which is indistinguishable from random (your first criteria), then a CSPRNG need not meet the second criteria. This can be seen by the observation that this definition relies only on the output, while the second criteria is also defined in terms of the internal state.
