Review of An Introduction to Number Theory with Cryptography by James S. Kraft and Lawrence Washington

"Review of An Introduction to Number Theory with Cryptography by James S. Kraft and Lawrence Washington." Cryptologia, 41(1), pp. 90–91

Notes

¹Washington and Wade Trappe are authors of a standard cryptography textbook, Introduction to Cryptography with Coding Theory.

²Some preliminary material (geometric series, mathematical induction, Pascal’s triangle and the binomial theorem, and Fibonacci numbers) are included (with exercises) in an appendix.

³The topics are primality and factorization, geometry of numbers, arithmetic functions, continued fractions, Gaussian integers, algebraic integers, analytic methods, and Fermat’s Last Theorem.

⁴Chapter 17, which is an epilogue on Fermat’s Last Theorem and elliptic curves, has no exercises.

⁵The exercise sets contain “check your understanding” problems with answers, exercises arranged by section (with answers or hints for the odd-numbered problems), suggestions for projects (i.e., harder problems), and “computer explorations.”
