Book excerpt: Le domaine de la cryptologie a, en quelques années, envahi notre quotidien, sans que nous en ayons toujours pleinement conscience (dossier médical, opérations sur compte en banque, badge électronique, carte de transport etc.). Elle rassemble aujourd’hui un ensemble de méthodes destinées à protéger toute information contre une observation ou une intrusion malveillante. Avec l’essor des réseaux de télécommunication et la banalisation des données enregistrées, les problèmes de sécurité (liés initialement aux informations échangées dans les milieux militaires et gouvernementaux) concernent un ensemble de plus en plus large de la population. La cryptologie est la réunion de deux disciplines qui s’alimentent l’une l’autre : la cryptographie (codeur) et la cryptanalyse (briseur de code). Après avoir décrit dans un premier chapitre les procédés de chiffrement traditionnels depuis l’Antiquité jusqu’au XXe siècle, l’auteur consacre les chapitres suivants aux procédés actuels comme la cryptologie à clé publique, la cryptoanalyse, l’utilisation de ces technique dans notre quotidien ainsi que les perspectives.

Book excerpt: La 4ème de couv. indique : "L'histoire de la cryptographie est celle d'un combat sans merci entre ceux qui ont quelquechose à cacher et ceux qui aimeraient bien découvrir ce qu'on leur cache. Au temps de César, déjà les généraux permutaient les lettres des messages envoyés à leurs armées. La méthode s'est perfectionnée pour aboutir, sous l'ère industrielle, à des machines à crypter dont la plus célèbre fut Enigma. Outre le domaine militaire, l'usage d'un code comme le Morse a installé l'idée de communiquer à distance... Aujourd'hui la cryptographie est omniprésente. Systèmes informatiques, terminaux de cartes bleues, téléphones mobiles sont équipés de protocoles de sécurité que défient les pirates des temps modernes. Sur le champ de bataille, les armes sont mathématiques et la plus redoutable se nomme la factorisation de grands nombres."

Available in PDF, EPUB and Kindle. Book excerpt: La bibliographie de Jacques Lerot impressionne. Par son volume - tout au long de sa carriere, il a ete un auteur fecond - , mais aussi par sa qualite - ainsi, son Precis de linguistique generale (Paris, editions de Minuit, 1993) - et par l'ouverture d'esprit qu'elle manifeste. A l'occasion de son depart a la retraite, vingt et un amis - collegues de Belgique ou de l'etranger, anciens etudiants ou doctorants - se sont reunis a l'instigation de Heinz Bouillon pour proposer 18 articles, ecrits en francais, allemand, neerlandais ou anglais, quatre langues que Jacques Lerot pratique assidument. Comme les horizons de Jacques sont larges, les sujets etudies sont multiculturels, abordant des regions aussi bien proches que lointaines comme le Burundi ou Madagascar. Ils illustrent aussi la multiplicite des diverses approches possibles dans l'etude des faits de langue, passant de la linguistique a la litterature sans oublier la didactique. Dans sa vision scientifique, Jacques Lerot a toujours soutenu que toute explication avait sa place si l'on distingue des niveaux multiples. Gageons qu'il trouvera pour chacune des contributions ici offertes une belle place dans son systeme de pensee a lui.

Download or read book Fault Analysis in Cryptography written by Marc Joye and published by Springer Science & Business Media. This book was released on 2012-06-21 with total page 352 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the 1970s researchers noticed that radioactive particles produced by elements naturally present in packaging material could cause bits to flip in sensitive areas of electronic chips. Research into the effect of cosmic rays on semiconductors, an area of particular interest in the aerospace industry, led to methods of hardening electronic devices designed for harsh environments. Ultimately various mechanisms for fault creation and propagation were discovered, and in particular it was noted that many cryptographic algorithms succumb to so-called fault attacks. Preventing fault attacks without sacrificing performance is nontrivial and this is the subject of this book. Part I deals with side-channel analysis and its relevance to fault attacks. The chapters in Part II cover fault analysis in secret key cryptography, with chapters on block ciphers, fault analysis of DES and AES, countermeasures for symmetric-key ciphers, and countermeasures against attacks on AES. Part III deals with fault analysis in public key cryptography, with chapters dedicated to classical RSA and RSA-CRT implementations, elliptic curve cryptosystems and countermeasures using fault detection, devices resilient to fault injection attacks, lattice-based fault attacks on signatures, and fault attacks on pairing-based cryptography. Part IV examines fault attacks on stream ciphers and how faults interact with countermeasures used to prevent power analysis attacks. Finally, Part V contains chapters that explain how fault attacks are implemented, with chapters on fault injection technologies for microprocessors, and fault injection and key retrieval experiments on a widely used evaluation board. This is the first book on this topic and will be of interest to researchers and practitioners engaged with cryptographic engineering.
Download or read book Complexity of Lattice Problems written by Daniele Micciancio and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 229 pages. Available in PDF, EPUB and Kindle. Book excerpt: Lattices are geometric objects that can be pictorially described as the set of intersection points of an infinite, regular n-dimensional grid. De spite their apparent simplicity, lattices hide a rich combinatorial struc ture, which has attracted the attention of great mathematicians over the last two centuries. Not surprisingly, lattices have found numerous ap plications in mathematics and computer science, ranging from number theory and Diophantine approximation, to combinatorial optimization and cryptography. The study of lattices, specifically from a computational point of view, was marked by two major breakthroughs: the development of the LLL lattice reduction algorithm by Lenstra, Lenstra and Lovasz in the early 80's, and Ajtai's discovery of a connection between the worst-case and average-case hardness of certain lattice problems in the late 90's. The LLL algorithm, despite the relatively poor quality of the solution it gives in the worst case, allowed to devise polynomial time solutions to many classical problems in computer science. These include, solving integer programs in a fixed number of variables, factoring polynomials over the rationals, breaking knapsack based cryptosystems, and finding solutions to many other Diophantine and cryptanalysis problems.
Download or read book The American Black Chamber written by Herbert O. Yardley and published by Naval Institute Press. This book was released on 2013-01-15 with total page 403 pages. Available in PDF, EPUB and Kindle. Book excerpt: During the 1920s Herbert O. Yardley was chief of the first peacetime cryptanalytic organization in the United States, the ancestor of today's National Security Agency. Funded by the U.S. Army and the Department of State and working out of New York, his small and highly secret unit succeeded in breaking the diplomatic codes of several nations, including Japan. The decrypts played a critical role in U.S. diplomacy. Despite its extraordinary successes, the Black Chamber, as it came to known, was disbanded in 1929. President Hoover's new Secretary of State Henry L. Stimson refused to continue its funding with the now-famous comment, "Gentlemen do not read other people's mail." In 1931 a disappointed Yardley caused a sensation when he published this book and revealed to the world exactly what his agency had done with the secret and illegal cooperation of nearly the entire American cable industry. These revelations and Yardley's right to publish them set into motion a conflict that continues to this day: the right to freedom of expression versus national security. In addition to offering an exposé on post-World War I cryptology, the book is filled with exciting stories and personalities.
