Fortuna, in Roman religion, goddess of chance or lot who became identified with the Greek Tyche; the original Italian deity was probably regarded as the bearer of prosperity and increase. As such she resembles a fertility. Fortuna (PRNG) - Wikipedia. Fortuna is a cryptographically secure pseudorandom number generator (PRNG) devised by Bruce Schneier and Niels Ferguson and published in 2. It is named after Fortuna, the Roman goddess of chance. 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. Generator. Practical Cryptography suggests AES, Serpent or Twofish. The basic idea is to run the cipher in counter mode, encrypting successive values of an incrementing counter. On its own, this would produce statistically identifiable deviations from randomness; for instance, generating 2. Therefore, the key is changed periodically: no more than 1 Mi.

HOUSTON, May 10, 2016 –Fortuna Resources Holdings, LLC (“Fortuna”) announced today. B of data is generated without a key change. The key is also changed after every data request (however small), so that a key compromise doesn't endanger old RNG outputs. Entropy accumulator. Thus, the kth pool is used only 1/2k of the time. Higher- numbered pools, in other words, (1) contribute to reseedings less frequently but (2) collect a larger amount of entropy between reseedings. Reseeding is performed by hashing the specified entropy pools into the block cipher's key using two iterations of SHA- 2. Seeding. And that pool will be used at an interval proportional to the amount of entropy in question. Therefore, the system will always recover from an injection attack, and the time it takes to do so is at most a constant factor greater than the theoretical time it could take if we were able to identify which sources of entropy were corrupt and which not. This conclusion depends on there being enough pools. Fortuna uses 3. 2 pools, and restricts reseeding to happen at most 1. Running out of pools would then take about 1. Ferguson and Schneier deem long enough for practical purposes. More paranoid implementors, or ones requiring the generation of random data at a colossal rate and correspondingly frequent reseeding, could use a larger number of pools. Alternatives. Yarrow required each source of entropy to be accompanied by a mechanism for estimating the actual entropy supplied, and used only two pools; and its suggested embodiment (called Yarrow- 1.
