Book excerpt: Scientific Essay from the year 2022 in the subject Computer Science - IT-Security, grade: 75%, language: English, abstract: This report will select one of the obsolete cryptographic algorithms, analyse it, discuss one of its vulnerabilities, and suggest a modern algorithm to address this weakness. The business Management system (BMS) is a powerful management tool that helps an organisation's management build, create, control, and monitor business activities. Currently, it evolved and has become the backbone of strategic planning and everyday business operations. BMS has the technical infrastructure, such as access control, to protect information from unauthorised access. Still, it can not be used alone to preserve the confidentiality and integrity of information handled against different challenges such as secure system development and maintenance, operation and physical security and compliance with regulations. Cryptography plays an essential role in protecting data's confidentiality and integrity, which might be hosted within the companies' premises or outsourced to a cloud service. Furthermore, cryptography protect information processed and transmitted within a communication medium. BMS incorporates many algorithms that serve this purpose; however, some of them are legacy or obsolete, such as RC2, RC4, DES, 3DES, MD2, MD4, MD5, SHA-1, and no longer recommended to be used because they are proved to be vulnerable.

Download or read book Cryptographic Boolean Functions and Applications written by Thomas W. Cusick and published by Academic Press. This book was released on 2017-03-31 with total page 290 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cryptographic Boolean Functions and Applications, Second Edition is designed to be a comprehensive reference for the use of Boolean functions in modern cryptography. While the vast majority of research on cryptographic Boolean functions has been achieved since the 1970s, when cryptography began to be widely used in everyday transactions, in particular banking, relevant material is scattered over hundreds of journal articles, conference proceedings, books, reports and notes, some of them only available online. This book follows the previous edition in sifting through this compendium and gathering the most significant information in one concise reference book. The work therefore encompasses over 600 citations, covering every aspect of the applications of cryptographic Boolean functions. Since 2008, the subject has seen a very large number of new results, and in response, the authors have prepared a new chapter on special functions. The new edition brings 100 completely new references and an expansion of 50 new pages, along with heavy revision throughout the text. - Presents a foundational approach, beginning with the basics of the necessary theory, then progressing to more complex content - Includes major concepts that are presented with complete proofs, with an emphasis on how they can be applied - Includes an extensive list of references, including 100 new to this edition that were chosen to highlight relevant topics - Contains a section on special functions and all-new numerical examples

This book was released on 2018-01-10 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Data Encryption Standard (Des) That is the permuted input has bit 58 of the input as its first bit, bit 50 as its second bit, and so on with bit 7 as its last bit. The permuted input block is then the input to a complex key-dependent computation described below. The output of that computation, called the preoutput, is then subjected to the following permutation which is the inverse of the initial permutation: That is, the output of the algorithm has bit 40 of the preoutput block as its first bit, bit 8 as its second bit, and so on, until bit 25 of the preoutput block is the last bit of the output. The computation which uses the permuted input block as its input to produce the preoutput block consists, but for a final interchange of blocks, of 16 iterations of a calculation that is described below in terms of the cipher function f which operates on two blocks, one of 32 bits and one of 48 bits, and produces a block of 32 bits. Let the 64 bits of the input block to an iteration consist of a 32 bit block L followed by a 32 bit block R. Using the notation defined in the introduction, the input block is then lr.

Download or read book Algebraic Aspects of the Advanced Encryption Standard written by Carlos Cid and published by Springer Science & Business Media. This book was released on 2006-11-24 with total page 145 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Belgian block cipher Rijndael was chosen in 2000 by the U.S. government’s National Institute of Standards and Technology (NIST) to be the successor to the Data Encryption Standard. Rijndael was subsequently standardized as the Advanced Encryption Standard (AES), which is potentially the world’s most important block cipher. In 2002, some new analytical techniques were suggested that may have a dramatic effect on the security of the AES. Existing analytical techniques for block ciphers depend heavily on a statistical approach, whereas these new techniques are algebraic in nature. Algebraic Aspects of the Advanced Encryption Standard, appearing five years after publication of the AES, presents the state of the art for the use of such algebraic techniques in analyzing the AES. The primary audience for this work includes academic and industry researchers in cryptology; the book is also suitable for advanced-level students.

Book excerpt: A How-to Guide for Implementing Algorithms and Protocols Addressing real-world implementation issues, Understanding and Applying Cryptography and Data Security emphasizes cryptographic algorithm and protocol implementation in hardware, software, and embedded systems. Derived from the author’s teaching notes and research publications, the text is designed for electrical engineering and computer science courses. Provides the Foundation for Constructing Cryptographic Protocols The first several chapters present various types of symmetric-key cryptographic algorithms. These chapters examine basic substitution ciphers, cryptanalysis, the Data Encryption Standard (DES), and the Advanced Encryption Standard (AES). Subsequent chapters on public-key cryptographic algorithms cover the underlying mathematics behind the computation of inverses, the use of fast exponentiation techniques, tradeoffs between public- and symmetric-key algorithms, and the minimum key lengths necessary to maintain acceptable levels of security. The final chapters present the components needed for the creation of cryptographic protocols and investigate different security services and their impact on the construction of cryptographic protocols. Offers Implementation Comparisons By examining tradeoffs between code size, hardware logic resource requirements, memory usage, speed and throughput, power consumption, and more, this textbook provides students with a feel for what they may encounter in actual job situations. A solutions manual is available to qualified instructors with course adoptions.
