【国外标准】 Financial Services - Random Number Generation Part 2: Entropy Sources

ANSI X9.82 is concerned with the generation of random bits, primarily for use in cryptographic applications. While there has been extensive research on the subject of generating (pseudo)random bits using a Random Bit Generator (RBG) and an unknown seed value, creating such an unknown value has not been as well documented. As Part 1 of this Standard establishes, the only way for this seed value to provide real security is for it to be obtained from a source that provides sufficient entropy. Directly or indirectly, the seeding of an RBG will rely upon a non-deterministic process ?i.e., an entropy source. This part of ANS X9.82 describes the properties that an entropy source must have to make it suitable for use by cryptographic random bit generators.
