Uncracked Codes and Ciphers

Gr 9 Up—In today's predominantly digital environment, using encryption and decryption to ensure security is imperative, making cryptography a vital industry. The art and science behind code breaking are examined, from ancient history to the present day. The authors introduce types of codes, ciphers, and algorithms, citing famous cases such as the Zodiac killer and the Navajo code talkers. Renowned cryptographers from a variety of historical periods, some more well known than others, are also presented. While some volumes are very technical, going into the mechanics and science behind cryptography, others are more narrative-driven, unraveling the stories behind the toughest cryptograms. The ethical implications associated with modern hacking practices are explored, with references made to relevant cyberattacks and large-scale breaches to illustrate cryptography's many practical applications for national defense and for corporate and personal safety. An exhaustive list of print and nonprint resources as well as international and governmental agencies is provided.
