Abstract[English]
Large prime numbers are used for keys generation in cryptography. It is computationally slow and requires large memory storage to generate large prime numbers in sieving methods. Other prime number generators rely on generating probable prime numbers and then test them for primality. This invention seeks to resolve these two issues. An interval is defined to search for large prime numbers. Equations are derived to locate all odd composite numbers within the interval. The gaps between two consecutive composite numbers will then give true prime numbers. The general flow is shown in Figure 1.
