A Computational Introduction to Number Theory and Algebra

A Computational Introduction to Number Theory and Algebra provides a comprehensive foundation in mathematical concepts essential for cryptography and computer science. The text covers fundamental topics including divisibility, congruences, finite fields, and probabilistic algorithms. The book progresses from basic number theory through abstract algebra to advanced computational methods. Mathematical proofs and concrete examples demonstrate the practical applications of theoretical concepts. Clear explanations and exercise problems appear throughout the text to reinforce learning. Programming examples use pseudocode that can be implemented in any language. The work bridges pure mathematics and computer science, emphasizing the intersection of theoretical foundations with real-world computational problems. Its approach reflects the growing importance of number theory and algebra in modern cryptography and digital security.
