Abstract:
Number theory serves as a foundational pillar in the realm of cryptography and security, offering profound insights and methodologies for safeguarding sensitive information in digital communication. This research paper delves into the intricate relationship between number theory, cryptography, and security, elucidating the profound significance of prime numbers, modular arithmetic, and discrete logarithms in cryptographic algorithms. Through a comprehensive analysis of various cryptographic schemes such as RSA, Diffie-Hellman, and elliptic curve cryptography, this paper highlights the pivotal role of number theory in developing robust encryption techniques to protect data integrity, confidentiality, and authenticity in modern information systems. Furthermore, it explores emerging trends and challenges in cryptographic protocols, emphasizing the continuous evolution of number-theoretic concepts to mitigate security vulnerabilities and adapt to the dynamic landscape of cyber threats. By synthesizing theoretical foundations with practical applications, this paper underscores the indispensability of number theory in shaping the landscape of digital security and fostering trust in the digital age.
