Cryptography and Computational Number Theory

Cryptography is the practice of safeguarding communication by encoding electronic and computer-based exchanges, serving to protect information from unauthorized access. Modern cryptography relies on key principles such as confidentiality, authentication, non-repudiation, and data integrity. Using mathematical concepts, particularly computational number theory, cryptography encrypts messages to ensure their security. This book unfolds the innovative aspects of the fundamentals of cryptography, which will be crucial for the holistic understanding of the subject matter. This book discusses the core as well as modern approaches to the study of cryptography. Those with an interest in computers and cryptography would find this book helpful.
