In October 2000, the US National Institute of Standards and Technology selected the block cipher Rijndael as the Advanced Encryption Standard (AES). AES is expected to gradually replace the present Data Encryption Standard (DES) as the most widely applied data encryption technology. This book by the designers of the block cipher presents Rijndael from scratch. The underlying mathematics and the wide trail strategy as the basic design idea are explained in detail and the basics of differential and linear cryptanalysis are reworked. Subsequent chapters review all known attacks against the Rijndael structure and deal with implementation and optimization issues. Finally, other ciphers related to Rijndael are presented. This book is THE authoritative guide to the Rijndael algorithm and AES. Professionals, researchers, and students active or interested in data encryption will find it a valuable source of information and reference.
The 13th International Conference on Practice and Theory in Public Key Cryp- ' tography(PKC2010)washeldMay26-28,2010,attheEcoleNormaleSup' erieure (ENS) in Paris, France. PKC 2010 was sponsored by the International Associ- ' ation for Cryptologic Research (IACR), in cooperation with the Ecole Normale Sup' erieure (ENS) and the Institut National de Recherche en Informatique et en Automatique (INRIA). The General Chairs of the conference were Michel Abdalla and Pierre-Alain Fouque. The conference received a record number of 145 submissions and each s- missionwas assignedto at least 3 committee members. Submissions co-authored by members of the Program Committee were assigned to at least ?ve comm- tee members. Due to the large number of high-quality submissions, the review process was challenging and we are deeply grateful to the 34 committee m- bers and the 163 external reviewers for their outstanding work. After extensive discussions, the Program Committee selected 29 submissions for presentation during the conference and these are the articles that are included in this v- ume. The best paper was awardedto Petros Mol and Scott Yilek for their paper "Chosen-Ciphertext Security from Slightly Lossy Trapdoor Functions. " The - view process was run using the iChair software, written by Thomas Baign' eres and Matthieu Finiasz from EPFL, LASEC, Switzerland, and we are indebted to them for letting us use their software. The program also included two invited talks: it was a great honor to have Daniele Micciancio and Jacques Stern as invited speakers.

The 79 revised full papers presented were carefully reviewed and selected from 351 submissions. The papers are organized in the following topical sections: secure messaging; implementations and physical attacks prevention; authenticated and format-preserving encryption; cryptoanalysis; searchable encryption and differential privacy; secret sharing; encryption; symmetric cryptography; proofs of work and proofs of stake; proof tools; key exchange; symmetric cryptoanalysis; hashes and random oracles; trapdoor functions; round optimal MPC; foundations; lattices; lattice-based ZK; efficient MPC; quantum cryptography; MPC; garbling; information-theoretic MPC; oblivious transfer; non-malleable codes; zero knowledge; and obfuscation.
These are the proceedings of Eurocrypt 2008, the 27th Annual IACR Eu- crypt Conference. The conference was sponsored by the International Asso- ation for Cryptologic Research (www.iacr.org), this year in cooperation with Tubitak (www.tubitak.gov.tr). The Eurocrypt 2008 Program Committee (PC) consisted of 28 members whose names are listed on the next page. There were 163 papers submitted to the conference and the PC chose 31 of them. Each paper was assigned to at least three PC members, who either handled it themselves or assigned it to an external referee. After the reviews were submitted, the committee deliberated both online for severalweeks and?nally ina face-to-facemeetingheldinBristol. Papers were refereed anonymously, with PC papers having a minimum of ?ve reviewers. All of our deliberations were aided by theWeb Submission and- viewSoftware written and maintainedby Shai Halevi. In addition to noti?cation of the decision of the committee, authors received reviews; the default for any report given to the committee was that it should be available to the authors as well.
This book covers newly developed and novel Steganography techniques and algorithms. The book outlines techniques to provide security to a variety of applications using Steganography, with the goal of both hindering an adversary from decoding a hidden message, and also preventing an adversary from suspecting the existence of covert communications. The book looks into applying these newly designed and improved algorithms to provide a new and efficient Steganographic system, called Characteristic Region-Based Image Steganography (CR-BIS). The algorithms combine both the robustness of the Speeded-Up Robust Features technique (SURF) and Discrete Wavelet Transform (DWT) to achieve characteristic region Steganography synchronization. The book also touches on how to avoid hiding data in the whole image by dynamically selecting characteristic regions for the process of embedding. Applies and discusses innovative techniques for hiding text in a digital image file or even using it as a key to the encryption; Provides a variety of methods to achieve characteristic region Steganography synchronization; Shows how Steganography improves upon cryptography by using obscurity features.

Die Kommunikation ber das Internet ist quasi ffentlich: Dritte k nnen Nachrichten mitlesen, abfangen oder f lschen. Genauso kann ein Sender einer Nachricht behaupten, diese nie gesendet zu haben, und ein Empf nger kann behaupten, eine Nachricht nie erhalten zu haben. Abhilfe schafft die Kryptografie. Sie erm glicht nicht nur die Verschl sselung von Nachrichten, sondern auch digitale Unterschriften, die Authentifizierung und die Anonymisierung von Kommunikationspartnern. Das hier vorliegende Buch ist eine Einf hrung in die Kryptografie f r Studierende - von der symmetrischen ber die asymmetrische Verschl sselung bis hin zu Hash-Funktionen. Umfassend, keinesfalls oberfl chlich, aber ohne Vorwissen verst ndlich.
