"Though often invisible, cryptography plays a critical role in our everyday lives. It underpins the security of everything we do online, from our mobile phone calls, credit card payments, web searches, internet messaging, and cryptocurrencies to the use of smart devices like refrigerators, thermostats, and cars. Cryptography, broadly defied as a set of tools for establing security in cyberspace, enables us to protect and share our information. Longtime information security professor Keith Martin reveals the many crucial ways we all depend on encryption technology, demystifies its controversial applications, and explains the nuances behind alarming headlines about data breaches at banks, credit bureaus, and online retailers. Essential reading for anyone with a password, Cryptography offers a profound perspective on personal security, online and off."--Back cover.
