Fortuna is a cryptographically secure pseudorandom number generator (PRNG) devised by Bruce Schneier and Niels Ferguson and published in 2003. It is named after Fortuna, the Roman goddess of chance. == Design == Fortuna is a ''family'' of secure PRNGs; its design leaves some choices open to implementors. It is composed of the following pieces: * The generator itself, which once seeded will produce an indefinite quantity of pseudo-random data. * The entropy accumulator, which collects genuinely random data from various sources and uses it to reseed the generator when enough new randomness has arrived. * The seed file, which stores enough state to enable the computer to start generating random numbers as soon as it has booted. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Fortuna (PRNG)」の詳細全文を読む スポンサード リンク
