Solovay-Strassen Test

The Solovay-Strassen test is a probabilistic primality test used to determine whether a given integer is likely prime or composite. It is based on the properties of the Jacobi symbol and Euler's criterion in number theory. While not deterministic, it provides a fast and reliable method for primality testing with a high probability of correctness.

Also known as: Solovay Strassen primality test, Solovay-Strassen algorithm, SS test, Solovay Strassen, Solovay-Strassen primality algorithm

Why learn Solovay-Strassen Test?

Developers should learn this test when working in cryptography, security, or number theory applications that require efficient primality checks, such as generating large prime numbers for RSA encryption. It is particularly useful in scenarios where deterministic tests like the AKS primality test are too slow, and a probabilistic approach with a controllable error rate is acceptable.
