Randomness test. A randomness test (or test for randomness), in data evaluation, is a test used to analyze the distribution of a set of data to see whether it can be described as random (patternless). In stochastic modeling, as in some computer simulations, the hoped-for randomness of potential input data can be verified, by a formal test for ...
Andrew Yao proved in 1982 that a generator passing the next-bit test will pass all other polynomial-time statistical tests for randomness. [2] They hold up well under serious attack, even when part of their initial or running state becomes available to an attacker: [3] Every CSPRNG should withstand "state compromise extension attacks".
NIST SP 800-90A ("SP" stands for " special publication ") is a publication by the National Institute of Standards and Technology with the title Recommendation for Random Number Generation Using Deterministic Random Bit Generators. The publication contains the specification for three allegedly cryptographically secure pseudorandom number ...
The FIPS 140-2 standard is an information technology security approval program for cryptographic modules produced by private sector vendors who seek to have their products certified for use in government departments and regulated industries (such as financial and health-care institutions) that collect, store, transfer, share and disseminate ...
The tests are the monobit test (equal numbers of ones and zeros in the sequence), poker test (a special instance of the chi-squared test), runs test (counts the frequency of runs of various lengths), longruns test (checks whether there exists any run of length 34 or greater in 20 000 bits of the sequence)—both from BSI [21] and NIST, [22] and ...
The 140 series of Federal Information Processing Standards (FIPS) are U.S. government computer security standards that specify requirements for cryptographic modules. As of October 2020, FIPS 140-2 and FIPS 140-3 are both accepted as current and active. [1] FIPS 140-3 was approved on March 22, 2019 as the successor to FIPS 140-2 and became ...
FIPS 140-3. The Federal Information Processing Standard Publication 140-3 (FIPS PUB 140-3) [1][2] is a U.S. government computer security standard used to approve cryptographic modules. The title is Security Requirements for Cryptographic Modules. Initial publication was on March 22, 2019 and it supersedes FIPS 140-2.
Diffie–Hellman (DH) key exchange[nb 1] is a mathematical method of securely generating a symmetric cryptographic key over a public channel and was one of the first public-key protocols as conceived by Ralph Merkle and named after Whitfield Diffie and Martin Hellman. [1][2] DH is one of the earliest practical examples of public key exchange ...
