Junod and S. Vaudenay (2004) • New name: IDEA-NXT • Owned by Mediacrypt A.G. • Lai-Massey structure, like IDEA cipher • Two main ciphers: FOX64 and FOX128 • Byte-oriented design: byte are elements of GF(2 8) = GF(2)[x]/(x8+x7+x6+x5+x4 +x3+1) SBSeg 2008, Gramado, RS, Brazil The FOX Cipher Family • Each round of FOX64 uses a bijective mapping called f32 consisting of an MDS matrix, xor with two round subkeys, and an 8x8-bit S-box • Each round of FOX128 uses a bijective mapping called f64, consisting of an MDS matrix, xor with two round subkeys and an 8x8-bit S-box • To break the round symmetry, there is a linear transformation called orthomorphism (or) at the end of each round.

8 THE POLISH TRACE COMPOSED FROM COMMONLY AVAILABLE SOURCES BY LECH POLKOWSKI FOR IJCRS2017 FOREWORD It is a desire of many participants of conferences to learn as much as possible about the history and culture of he visited country and place and organizers try to satisfy this desire by providing excursions into attractive places and sites. IJCRS2017 also tries to take participants to historic sites of Warmia and Mazury and to show elements of local culture. As an innovation, we propose a booklet showing some achievements of Polish scientists and cryptographers, no doubt many of them are known universally, but some probably not. What bounds all personages described here is that they all suffered due to world wars, th efirst and the second. These wars ruined their homes, made them refugees and exiles, destroyed their archives and libraries, they lost many colleagues, friends and students but were lucky enough to save lives and in some cases to begin the career overseas. We begin with the person of Jan Czochralski, world famous metallurgist, discoverer of the technique of producing metal monocrystals `the Czochralski methode’ and inventor of duraluminum and the `bahnalloy’ who started his career and obtained its heights in Germany, later returned to Poland, became a professor at the Warsaw Polytechnical, played an important role in cultural life of Warsaw, lived in Warsaw through the second world war and the Warsaw Uprising of August-September 1944 and after the war was accused of cooperating ith occupying German forces and though judged innocent was literally erased from the public life and any information about him obliterated. -

A story by the President of the Institute of National Remembrance appears in the latest instalment of the "We Are Telling the World about Poland" series. This weekend, fifty media outlets around the world are publishing “Polish Innovators Have Changed the World”, another text by Jarosław Szarek in the “We Are Telling the World about Poland” project. This initiative of the New Media Institute is supported by the IPN, Foreign Ministry, National Bank and Polish Press Agency. France, Germany, Italy, Spain and Russia will be told about Poland, but the story is also headed for more exotic places, such as Venezuela, Kuwait or Singapore. This weekend, France will be reading it in the “Special Pologne” insert in the “L’Opinion” daily. President Szarek gives examples of Polish explorers, innovators and inventors, “Poles spurred the development of electronics, chemistry and aviation. They constructed portable mine detectors and broke the German Enigma, accelerating the end of the WW2,” writes the IPN’s President, and adds, In the early 1980s, when the world watched the struggle of Polish “Solidarity” and newspapers carried the name of John Paul II on their front pages, only few people knew that 90% of stainless steel almost everyone used daily, including in their kitchens, was produced through a process developed by the US-based Polish engineer Tadeusz Sendzimir, the “Edison of metallurgy . -

Encryption Block Cipher
10/29/2007 Encryption Encryption Block Cipher Dr.Talal Alkharobi 2 Block Cipher A symmetric key cipher which operates on fixed-length groups of bits, termed blocks, with an unvarying transformation. When encrypting, a block cipher take n-bit block of plaintext as input, and output a corresponding n-bit block of ciphertext. The exact transformation is controlled using a secret key. Decryption is similar: the decryption algorithm takes n-bit block of ciphertext together with the secret key, and yields the original n-bit block of plaintext. Mode of operation is used to encrypt messages longer than the block size. 1 Dr.Talal Alkharobi 10/29/2007 Encryption 3 Encryption 4 Decryption 2 Dr.Talal Alkharobi 10/29/2007 Encryption 5 Block Cipher Consists of two algorithms, encryption, E, and decryption, D. Both require two inputs: n-bits block of data and key of size k bits, The output is an n-bit block. Decryption is the inverse function of encryption: D(E(B,K),K) = B For each key K, E is a permutation over the set of input blocks. n Each key K selects one permutation from the possible set of 2 !. 6 Block Cipher The block size, n, is typically 64 or 128 bits, although some ciphers have a variable block size. 64 bits was the most common length until the mid-1990s, when new designs began to switch to 128-bit. Padding scheme is used to allow plaintexts of arbitrary lengths to be encrypted. Typical key sizes (k) include 40, 56, 64, 80, 128, 192 and 256 bits. -

The Effectiveness of Encryption Methods in Mitigating Information Technology Security Risks by TROY MOKOENA (215043290) A LIMITED SCOPE DISSERTATION submitted in fulfilment of the requirements for the degree MASTERS COMMERCII in COMPUTER AUDITING in the FACULTY OF ECONOMIC AND FINANCIAL SCIENCES at the UNIVERSITY OF JOHANNESBURG Supervisor: Jacob Mamaile Co-Supervisor: Rozanne Smith October 2016 ABSTRACT Data protection is a critical area that is currently receiving much attention worldwide. Easy access to the internet and an increase in information transfer over communication networks contributes greatly to the need for data to be protected. Reports of data breaches from corporations and government institutions across the world have increased. Data breaches are mostly executed through the internet and other networks. Data loss and breaches can have significant consequences for concerned parties, such as reputational damage and litigation, when personal information is exposed to unauthorised persons. -

Cryptanalysis Vs. Reality
Cryptanalysis vs. Reality Jean-Philippe Aumasson 1 / 54 Cryptanalysis is the study of methods for obtaining the meaning of encrypted information without access to the secret information that is normally required to do so. Wikipedia 2 / 54 Cryptanalysis is the study of methods for obtaining the meaning of encrypted information without access to the secret information that is normally required to do so. Wikipedia 3 / 54 The fundamental goal of a cryptanalyst is to violate one or several security notions for algorithms that claim, implicitly or explicitly, to satisfy these security notions. Antoine Joux, Algorithmic Cryptanalysis 4 / 54 Reality noun (pl. realities) 1. the state of things as they actually exist, as opposed to an idealistic or notional idea of them. 2. a thing that is actually experienced or seen. 3. the quality of being lifelike. 4. the state or quality of having exis- tence or substance. Compact Oxford English Dictionary 5 / 54 Cryptanalysis relies on an ATTACKER MODEL = assumptions on what the attacker can and cannot do All models are in simulacra, that is, simplified reflections of reality, but, despite their inherent falsity, they are nevertheless extremely useful G. Box, N. Draper, Empirical Model-Building and Response Surfaces 6 / 54 Cryptanalysis usually excludes methods of attack that do not primarily target weaknesses in the actual cryptography, such as bribery, physical coercion, burglary, keystroke logging, and social engineering, although these types of attack are an important concern and are often more effective Wikipedia 7 / 54 Cryptanalysis used to be tightly connected to reality 8 / 54 But times have changed 9 / 54 10 / 54 11 / 54 Broken in a model does not imply broken in reality! 12 / 54 Models’ language overlaps with real-world language: “attacks”, “broken” have multiple meanings Has cryptanalysis lost connection with reality? 13 / 54 Cryptography is usually bypassed. -
