Elementary Number Theory, Cryptography and Codes by Maria Welleda BaldoniEnglish | PDF(True) | 2009 | 530 Pages | ISBN : 3540691995 | 4.2 MB
In this volume one finds basic techniques from algebra and number theory (e.g. congruences, unique factorization domains, finite fields, quadratic residues, primality tests, continued fractions, etc.) which in recent years have proven to be extremely useful for applications to cryptography and coding theory.
