Published in 1999, The Code Book is widely considered the most accessible and comprehensive history of cryptography ever written. Simon Singh, a physicist and acclaimed science author, strips away the intimidating mathematical jargon. He replaces it with a gripping, narrative-driven history filled with political intrigue, espionage, and intellectual triumphs.
With the foundations laid, Singh turns to modern cryptography. This chapter introduces the revolutionary concept of public-key cryptography, perhaps the most important cryptographic breakthrough of the twentieth century. Singh explains the so-called “key-distribution problem”—how can two parties who have never met exchange a secret key securely over an insecure channel? The solution, asymmetric ciphers, transformed everything from e-commerce to digital privacy. Singh recounts the dramatic story of Rivest, Shamir, and Adleman, who developed the RSA cipher after a night of Passover celebration and mathematical inspiration. One of the book’s most memorable passages describes how Adleman initially wanted his name removed from the paper, thinking it would be “the least interesting paper I will ever be on”. RSA went on to become the most influential cipher in modern cryptography. the code book by simon singh pdf
