摘要: We study Pseudorandom Number Generators (PRNGs) as used in practice. first give a general security frame work for PRNGs, incorporating the attacks that users are typically concerned about. then analyze most popular ones, including ANSI X9.17 PRNG and FIPS 186 PRNG. Our results also suggest ways which these PRNGs can be made more efficient secure.
