This creation to cryptography employs a programming-oriented method of research an important cryptographic schemes in present use and the most cryptanalytic assaults opposed to them. dialogue of the theoretical elements, emphasizing particular protection definitions in line with methodological instruments corresponding to complexity and randomness, and of the mathematical features, with emphasis on number-theoretic algorithms and their purposes to cryptography and cryptanalysis, is built-in with the programming technique, hence supplying implementations of the algorithms and schemes in addition to examples of life like size.
A virtue of the author's procedure is using Maple as a programming surroundings during which not only the cryptographic primitives but in addition crucial cryptographic schemes are applied following the ideas of criteria our bodies similar to NIST, with the various identified cryptanalytic assaults carried out besides. the aim of the Maple implementations is to permit the reader scan and study, and as a result the writer comprises a variety of examples. The publication discusses vital fresh topics comparable to homomorphic encryption, identity-based cryptography and elliptic curve cryptography. The algorithms and schemes that are taken care of intimately and applied in Maple comprise AES and modes of operation, CMAC, GCM/GMAC, SHA-256, HMAC, RSA, Rabin, Elgamal, Paillier, Cocks IBE, DSA and ECDSA. additionally, a few lately brought schemes having fun with powerful safeguard houses, equivalent to RSA-OAEP, Rabin-SAEP, Cramer--Shoup, and PSS, also are mentioned and applied. at the cryptanalysis aspect, Maple implementations and examples are used to debate many vital algorithms, together with birthday and man-in-the-middle assaults, integer factorization algorithms similar to Pollard's rho and the quadratic sieve, and discrete log algorithms equivalent to baby-step giant-step, Pollard's rho, Pohlig--Hellman and the index calculus method.
This textbook is appropriate for complex undergraduate and graduate scholars of computing device technology, engineering and arithmetic, pleasing the necessities of varied different types of classes: a easy introductory path; a theoretically orientated path whose concentration is at the specific definition of defense innovations and on cryptographic schemes with reductionist defense proofs; a practice-oriented path requiring little mathematical historical past and with an emphasis on functions; or a mathematically complicated path addressed to scholars with an improved mathematical history. the most prerequisite is a simple wisdom of linear algebra and common calculus, and whereas a few wisdom of likelihood and summary algebra will be valuable, it isn't crucial as the publication comprises the mandatory historical past from those matters and, in addition, explores the number-theoretic fabric intimately. The e-book can also be a finished reference and is appropriate for self-study by means of practitioners and programmers.
