However, generally they are considerably slower (typically by a factor 2–10) than fast, non-cryptographic random number generators. These include: Stream ciphers. Popular choices are Salsa20 or ChaCha (often with the number of rounds reduced to 8 for speed), ISAAC, HC-128 and RC4. Block ciphers in counter mode.
This is a list of fictional countries from published works of fiction (books, films, television series, games, etc.). Fictional works describe all the countries in the following list as located somewhere on the surface of the Earth as we know it – as opposed to underground, inside the planet, on another world, or during a different "age" of the planet with a different physical geography.
Random number table. Random number tables have been used in statistics for tasks such as selected random samples. This was much more effective than manually selecting the random samples (with dice, cards, etc.). Nowadays, tables of random numbers have been replaced by computational random number generators . If carefully prepared, the filtering ...
Random. On Wikipedia and other sites running on MediaWiki, Special:Random can be used to access a random article in the main namespace; this feature is useful as a tool to generate a random article. Depending on your browser, it's also possible to load a random page using a keyboard shortcut (in Firefox, Edge, and Chrome Alt-Shift + X ).
Lottery machine. A lottery machine is the machine used to draw the winning numbers for a lottery . Early lotteries were done by drawing numbers, or winning tickets, from a container. In the UK, numbers of winning Premium Bonds (which were not strictly a lottery, but very similar in approach) were generated by an electronic machine called ERNIE .
Matching all four "regular" numbers wins the jackpot; matching the "bonus" ball wins $10 plus any money won for matching at least two of the four "regular" numbers.). DC-5, Florida's Pick 5, Georgia Five, Louisiana's Pick 5, Maryland's Pick 5, Ohio's Pick 5, Pennsylvania's Pick 5, and Virginia's Pick 5 also do not truly fit this category, as ...
A USB-pluggable hardware true random number generator. In computing, a hardware random number generator (HRNG), true random number generator (TRNG), non-deterministic random bit generator (NRBG), or physical random number generator is a device that generates random numbers from a physical process capable of producing entropy (in other words, the device always has access to a physical entropy ...
Random number generation is a process by which, often by means of a random number generator ( RNG ), a sequence of numbers or symbols that cannot be reasonably predicted better than by random chance is generated. This means that the particular outcome sequence will contain some patterns detectable in hindsight but impossible to foresee.
