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.

Excerpt from Federal Information Processing Standards Publication, Vol. 74: Guidelines for Implementing and Using the Nbs Data Encryption Standard Within the last decade, there has been a vast increase in the accumulation and communication of digital computer data in both the private and public sectors. Much of this information has a significant value, either directly or indirectly, and requires protection. It is common to find data transmissions which constitute monetary transfers of billions of dollars daily. Sensitive information concerning individuals, organizations, and corporate entities is collected by Federal agencies in accordance with statutory requirements and is processed in computer systems. This information requires some type of protection, and cryptographic protection may be specified by the authority responsible for the data. The nbs Data Encryption Standard must be employed when cryptographic protection is required for unclassified Federal adp data. The des Modes of Operation Standard [3] defines the methods or modes in which the des may be implemented. The rapid growth of computer data banks increases the potential threats to personal privacy. Since data banks often are accessible from remote computer terminals, there is a threat of easy and unauthorized access to personal information from any place in the data communications system. Such information has typically been scattered in remote locations, controlled under separate auspices, and physically or administratively protected. With a telecommunications network of computer systems, What was previously a laborious job of assembling comprehensive dossiers on individuals may become a simple task. Thus, both valuable and sensitive information require protection against unauthorized disclosure and modification. Encryption is a tool which may be used in data security applications. It is not a panacea. With improper implementation and use, data encryption may only provide an illusion of security. With inadequate understanding of encryption applications, data encryption could deter the utilization of other needed protection techniques. However, with proper management controls, adequate implementation specifications, and applicable usage guidelines, data encryption will not only aid in protecting data communications but can provide protection for a myriad of specific data processing applications.

An authoritative and comprehensive guide to the Rijndael algorithm and 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, written 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.

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.

DES, the Data Encryption Standard, is the best known and most widely used civilian cryptosystem. It was developed by IBM and adopted as a US national standard in the mid 1970`s, and had resisted all attacks in the last 15 years. This book presents the first successful attack which can break the full 16 round DES faster than via exhaustive search. It describes in full detail, the novel technique of Differential Cryptanalysis, and demonstrates its applicability to a wide variety of cryptosystems and hash functions, including FEAL, Khafre, REDOC-II, LOKI, Lucifer, Snefru, N-Hash, and many modified versions of DES. The methodology used offers valuable insights to anyone interested in data security and cryptography, and points out the intricacies of developing, evaluating, testing, and implementing such schemes. This book was written by two of the field`s leading researchers, and describes state-of-the-art research in a clear and completely contained manner.
