NUMBER THEORY IN SCIENCE AND COMMUNICATION - WITH APPLICATION IN CRYPTOGRAPHY, PHYSICS, DIGITAL INF.

Number Theory in Science and Communication is a well-known introduction for non-mathematicians to this fascinating and useful branch of applied mathematics. It stresses intuitive understanding rather than abstract theory and highlights important concepts such as continued fractions, the golden ratio, quadratic residues and Chinese remainders, trapdoor functions, pseudo primes and primitive elements. Their applications to problems in the real world are one of the main themes of the book. This revised fifth edition is augmented by recent advances in coding theory, permutations and derangements and a chapter on quantum cryptography.
