The RSA algorithm works because, when n is sufficiently large, deriving d from a known e and n will be an impractically long calculation — unless we know p, in which case we can use the shortcut ...

It’s very difficult to factor a given large number into primes. For example, ... To explain how the RSA algorithm works, I need to tell you first about something called Fermat’s little theorem.

Factoring large numbers. The paper is called “Fast Factoring Integers by SVP Algorithms” and it was written by Claus Schnorr, 77, a respected cryptographer who retired from Johann Wolfgang ...

The RSA algorithm is but one of many systems where a set of mathematical theorems, often from number theory, can be synthesised to construct an encryption scheme.

Prime numbers are fundamental to the most common type of encryption used today: the RSA algorithm. The RSA algorithm was named after the three mathematicians who first publicly unveiled it in 1977.

The RSA algorithm is the most popular and best understood ... Computers don't do well with arbitrarily large numbers. ... Let's make this more concrete with an example. Take the prime numbers 13 ...

That’s because the secret prime numbers that underpin the security of an RSA key are easy to calculate using Shor’s algorithm. Computing the same primes using classical computing takes ...
