Prime Numbers and Their Role in Modern Cryptography

Abstract

Prime numbers form the foundation of modern cryptography and play a crucial role in securing digital communication systems. Their unique mathematical properties make them highly suitable for encryption algorithms used in banking, e-commerce, military communication, and internet security. Modern cryptographic techniques such as RSA encryption rely heavily on the difficulty of factoring large prime numbers, which ensures data confidentiality and protection against unauthorized access. the concept of prime numbers and explores their significance in cryptographic systems. It discusses the mathematical principles behind public-key encryption, key generation, and secure data transmission. the practical applications of prime numbers in cybersecurity, digital signatures, authentication protocols, and blockchain technology. Furthermore, the challenges faced in cryptography due to advancements in computational power and quantum computing. Through this study, it becomes evident that prime numbers continue to be essential in maintaining digital security and protecting sensitive information in the modern technological world.
