Mathematics论文模板 – The Evolution of Cryptography: From Classical Ciphers to Quantum Computing


This essay examines the evolution of cryptography from its origins in classical ciphers to the current challenges posed by quantum computing. By tracing the mathematical underpinnings of cryptographic methods, the essay highlights the ongoing arms race between code makers and code breakers that has been significantly influenced by advancements in mathematics.


Cryptography is a cornerstone of secure communication in the digital age. The progression from simple substitution ciphers to complex algorithms like RSA and ECC has been driven largely by mathematical discoveries. Today, the emergence of quantum computing threatens to undermine these cryptographic systems, prompting a search for new, quantum-resistant solutions.
