The Miller–Rabin primality test or Rabin–Miller primality test is a probabilistic primality test: an algorithm which determines whether a given number is likely to be prime, similar to the Fermat primality test and the Solovay–Strassen primality test. It is of historical significance in the search for a polynomial-time deterministic ...
The Miller–Rabin and the Solovay–Strassen primality tests are simple and are much faster than other general primality tests. One method of improving efficiency further in some cases is the Frobenius pseudoprimality test ; a round of this test takes about three times as long as a round of Miller–Rabin, but achieves a probability bound ...

It's no secret that fraud is on the rise these days, and the troubled economic times have led even more people to latch on to the possibility of a quick buck. One common scam is a form of wire ...
The Miller–Rabin primality test uses the following extension of Fermat's little theorem: [14] If p is an odd prime and p − 1 = 2 s d with s > 0 and d odd > 0, then for every a coprime to p, either a d ≡ 1 (mod p) or there exists r such that 0 ≤ r < s and a 2 r d ≡ −1 (mod p).
The letters, received by several residents in January, contain what looks like a $199 check that purports to be a “Registration Fee Voucher” from “County Deed Records.”

The Spanish Prisoner scam—and its modern variant, the advance-fee scam or "Nigerian letter scam"—involves enlisting the mark to aid in retrieving some stolen money from its hiding place. The victim sometimes believes they can cheat the con artists out of their money, but anyone trying this has already fallen for the essential con by ...
