    PRINCE { A Low-latency Block Cipher for Pervasive Computing Applications Extended Abstract? Julia Borghoff1??, Anne Canteaut1;2???, Tim G¨uneysu3, Elif Bilge Kavun3, Miroslav Knezevic4, Lars R. Knudsen1, Gregor Leander1y, Ventzislav Nikov4, Christof Paar3, Christian Rechberger1, Peter Rombouts4, Søren S. Thomsen1, and Tolga Yal¸cın3 1 Technical University of Denmark 2 INRIA, Paris-Rocquencourt, France 3 Ruhr-University Bochum, Germany 4 NXP Semiconductors, Leuven, Belgium Abstract. This paper presents a block cipher that is optimized with respect to latency when implemented in hardware. Such ciphers are de- sirable for many future pervasive applications with real-time security needs. Our cipher, named PRINCE, allows encryption of data within one clock cycle with a very competitive chip area compared to known solutions. The fully unrolled fashion in which such algorithms need to be implemented calls for innovative design choices. The number of rounds must be moderate and rounds must have short delays in hardware. At the same time, the traditional need that a cipher has to be iterative with very similar round functions disappears, an observation that increases the design space for the algorithm. An important further requirement is that realizing decryption and encryption results in minimum additional costs. PRINCE is designed in such a way that the overhead for decryp- tion on top of encryption is negligible. More precisely for our cipher it holds that decryption for one key corresponds to encryption with a re- lated key. This property we refer to as α-reflection is of independent interest and we prove its soundness against generic attacks. 1 Introduction The area of lightweight cryptography, i.e., ciphers with particularly low imple- mentation costs, has drawn considerable attention over the last years.

However, a number of attacks are mounted on these type of ciphers. Cellular Automata (CA) has recently been chosen as a suitable structure for crypto-primitives. In this work, a stream cipher is presented based on hybrid CA. The stream cipher takes 128 bit key and 128 bit initialization vector (IV) as input. It is designed to produce 2128 random keystream bits and initialization phase is made faster 4 times than that of Grain-128.

  • Construction of Lightweight S-Boxes Using Feistel and MISTY Structures (Full Version?)??
    Construction of Lightweight S-Boxes using Feistel and MISTY structures (Full Version?)?? Anne Canteaut, S´ebastienDuval, and Ga¨etanLeurent Inria, project-team SECRET, France fAnne.Canteaut, Sebastien.Duval, [email protected] Abstract. The aim of this work is to find large S-Boxes, typically operating on 8 bits, having both good cryptographic properties and a low implementation cost. Such S-Boxes are suitable building-blocks in many lightweight block ciphers since they may achieve a better security level than designs based directly on smaller S-Boxes. We focus on S-Boxes corresponding to three rounds of a balanced Feistel and of a balanced MISTY structure, and generalize the recent results by Li and Wang on the best differential uniformity and linearity offered by such a construction. Most notably, we prove that Feistel networks supersede MISTY networks for the construction of 8-bit permutations. Based on these results, we also provide a particular instantiation of an 8-bit permutation with better properties than the S-Boxes used in several ciphers, including Robin, Fantomas or CRYPTON. Keywords: S-Box, Feistel network, MISTY network, Lightweight block-cipher. 1 Introduction A secure block cipher must follow Shannon's criteria and provide confusion and diffusion [42]. In most cases, confusion is achieved with small substitution boxes (S-Boxes) operating on parts of the state (usually bytes) in parallel, and diffusion is achieved with linear operations mixing the state. The security of the cipher is then strongly dependent on the cryptographic properties of the S-Boxes. For instance, the AES uses an 8-bit S-Box based on the inversion in the finite field with 28 elements.

  • Adapting Rigidity to Symmetric Cryptography: Towards “Unswerving” Designs∗
    Adapting Rigidity to Symmetric Cryptography: Towards “Unswerving” Designs∗ Orr Dunkelman1 and Léo Perrin2 1 Computer Science Department, University of Haifa, Haifa, Israel; [email protected] 2 Inria, Paris, France; [email protected] Abstract. While designers of cryptographic algorithms are rarely considered as potential adversaries, past examples, such as the standardization of the Dual EC PRNG highlights that the story might be more complicated. To prevent the existence of backdoors, the concept of rigidity was introduced in the specific context of curve generation. The idea is to first state a strict scope statement for the properties that the curve needs to have and then pick e.g. the one with the smallest parameters. The aim is to ensure that the designers did not have the degrees of freedom that allows the addition of a trapdoor. In this paper, we apply this approach to symmetric algorithms. The task is challenging because the corresponding primitives are more complex: they consist of several sub- components of different types, and the properties required by these sub-components to achieve the desired security level are not as clearly defined. Furthermore, security often comes in this case from the interplay between these components rather than from their individual properties. In this paper, we argue that it is nevertheless necessary to demand that symmetric algorithms have a similar but, due to their different nature, more complex property which we call “unswervingness”. We motivate this need via a study of the literature on symmetric “kleptography” and via the study of some real-world standards. We then suggest some guidelines that could be used to leverage the unswervingness of a symmetric algorithm to standardize a highly trusted and equally safe variant of it.

  • Symmetric Cryptography
    Security Issues in Cloud Computing Modern Cryptography I { Symmetric Cryptography Peter Schwabe October 14, 2011 The binary alphabet So far we considered the alphabet A; B; : : : ; Z, and noted that it could also be written as 0;:::; 25. Encryption used addition modulo 26. Modern cryptography is targeted at computations carried out by a computer, it typically uses the alphabet 0; 1 (binary alphabet). • We call a letter at this alphabet bit. • A word of length 8 is called a byte. • We use the term n-bit string for a word of length n. • Most important operation is addition modulo 2, denoted ⊕, we call this operation xor (exclusive or). This operation can be extended to n-bit strings by applying it letter-wise, for example: 0 1 0 1 1 1 0 1 ⊕ 1 1 1 0 1 0 0 1 1 0 1 1 0 1 0 0 • Addition is the same as subtraction modulo 2. Adding (xoring) the same value twice results in the orignial value. • All information stored on typical computers is represented as words over this al- phabet. Stream ciphers Recall Vernam's cipher: Encryption is performed by adding (now: xoring) a random key stream to the message. The main disadvantage is that the random key needs to be as long as the message. 1 Idea: Use a relatively short random key. Use that to deterministically generate a random-looking (pseudo-random) key stream, xor this with the message. To obtain different key streams from the same key one usually uses a non-secret initalization vector (or nonce), as additional input.
