THE EULER-FERMAT THEOREM AND RSA CRYPTOGRAPHY Fermat’s Little Theorem states that, for every integer x and every prime p, the number xp x is divisible by p. Equivalently, for a prime p and an integer x which is not divisible by p, the di erence xp 1 1 is divisible by p. This last

Two theorems that play important roles in public-key cryptography are Fermat’s theorem and Euler’s theorem. Fermat’s Theorem Fermat’s theorem states the following: If p is prime and a is a positive integer not divisible by p, then
In plain English, it's the number of numbers less than or equal to x which are also coprime to it. For any given prime p, every number less than itself is ...
FERMAT’S AND EULER’S THEOREMS. Two theorems that play important roles in public-key cryptography are Fermat’s theorem and Euler’s theorem. Fermat’s Theorem. Fermat’s theorem states the following: If p is prime and a is a positive integer not divisible by p, then
Fermat's little theorem is the basis for the Fermat primality test and is one of the fundamental results of elementary number theory. The theorem is named after ...

And amazingly he just stumbled onto Fermat's Little Theorem. Given A colors and strings of length P, which are prime, the number of possible strings is A times A times A, P times, or A to the power of P. And when he removed the monocolored strings, he subtracts exactly A strings, since there are one for each color.

if necessary we may assume that x is divisible by q and not by p, so that Fermat’s Little Theorem (applied to xq 1 (rather than x) and p gives (xq 1)p 1 = 1 + kp for some nonnegative integers k, and xx˚(n) x= x[x(p 1)(q 1) 1] = kpx, which is divisible by n= pq, since x is divisible by q. This leads to the following procedure of RSA cryptography.
