WebNov 28, 2024 · Cryptography is the practice of writing and solving codes. A cryptographer is responsible for converting plain data into an encrypted format. Cryptography itself is an ancient field. For millennia, people have used codes to protect their secrets. Modern cryptography is the same; what’s different is the nature of the codes and the methods … WebThis text provides an ideal introduction for mathematics and computer science students to the mathematical foundations of modern cryptography. The book includes an extensive bibliography and index; supplementary materials are available online. The book covers a variety of topics that are considered central to mathematical cryptography.
