A cryptographically secure pseudorandom number generator (CSPRNG) or cryptographic pseudorandom number generator (CPRNG) is a pseudorandom number generator (PRNG) with properties that make it suitable for use in cryptography. It is also loosely known as a cryptographic random number generator (CRNG) (see Random number generation § "True" vs. pseudo-random numbers). WebCSPRNG 如何做到不可预测. 上一篇文章 我们提到了实现伪随机数生成器 PRNG 的一种经典算法: 线性同余法. 我们也提到了线性同余法由于无法做到不可预测而不能成为密码学安全的算法, 如果对其加以改进使做到不可预测，我们就能够得到密码学安全的随机数生成器 ...

For instance, if an attacker sees the result of many invocations, it needs to still be hard to predict the result of any future invocation ... philippine food service industry

WebDell BSAFE, formerly known as RSA BSAFE, is a FIPS 140-2 validated cryptography library, available in both C and Java. BSAFE was initially created by RSA Security, which was purchased by EMC and then, in turn, by Dell. When Dell sold the RSA business to Symphony Technology Group in 2024, Dell elected to retain the BSAFE product line. … Web多くのprngはcsprngとしては不適であり、上記の2つを満足しない。第一にprngの出力は統計的に無作為に見えるが、リバースエンジニアリングには耐性がない。従って、アルゴリズムを解析することで特別な統計的試験を設計でき、prng の出力が真の乱数では ...
