Cryptography

Cryptography: Theory and Practice, 4th Edition, provides an introduction to the fundamentals and modern developments of cryptography. Intended for instructors and students, the textbook combines theoretical principles with an exploration of practical methods and secure protocols.

The volume covers central topics such as the sponge construction for hash functions in the SHA-3 standard, key distribution techniques for sensor networks, and the fundamentals of visual cryptography for dividing secret visual messages into shares that reconstruct the original secret.

In addition to practical schemes, the text includes a mathematical appendix that summarizes definitions and core results in number theory and algebra.
