Primality Testing
Primality testing is a method used to determine whether a given number is a prime number, which means it has no positive divisors other than 1 and itself. This process is essential in fields like cryptography, where prime numbers play a crucial role in securing data. Various algorithms exist for primality testing, ranging from simple trial division to more complex methods like the Miller-Rabin test.
The efficiency of primality testing has improved significantly with advancements in computer science. Some algorithms can quickly identify large prime numbers, making them suitable for applications in public key cryptography and secure communications. As technology evolves, the search for faster and more reliable primality tests continues.
