Objective The Japanese government aims at joining in the most advanced IT nations in the world within the next 5 years as a consequence of executing e-Japan Strategy. We have to ensure the security and reliability of the advanced info-communications networks in Japan for realization of our target. In particular, unbiased evaluation and standardization of cryptographic techniques are required as a basic item for the spread of digital authentication schemes like digital signatures and consequently for the construction of the electronic government, which is the governmental execution of e-Japan Strategy. For this reason, following the last year project, we call for submitting cryptographic techniques, scrutinize the submitted cryptographic techniques, evaluate their security and performance and publicize the results as the CRYPTREC report 2001. The CRYPTREC report 2001 is supposed to be employed by Japanese government in many ways for their selection of cryptographic techniques used for constructing the electronic government. 1/27 2.

Prof., Dept. of Computer Science, Rani Anna Govt College for Women, Tirunelveli] 2 Assoc. Prof., Dept. of Computer Science, Dr. Ambedkar Govt Arts College, Chennai, India 3Assoc. Prof., Dept. of Computer Science, Womens Christian College, Nagercoil, India E-mail: [email protected] ABSTRACT Secure transmission of message was the concern of early men. Several techniques have been developed ever since to assure that the message is understandable only by the sender and the receiver while it would be meaningless to others. In this century, cryptography has gained much significance. This paper proposes a scheme to generate a Dynamic Key-dependent S-Box for the SubBytes Transformation used in Cryptographic Techniques. Keywords: Hamming weight, Hamming Distance, confidentiality, Dynamic Key dependent S-Box 1. INTRODUCTION Today communication networks transfer enormous volume of data. Information related to healthcare, defense and business transactions are either confidential or private and warranting security has become more and more challenging as many communication channels are arbitrated by attackers. Cryptographic techniques allow the sender and receiver to communicate secretly by transforming a plain message into meaningless form and then retransforming that back to its original form. Confidentiality is the foremost objective of cryptography. Even though cryptographic systems warrant security to sensitive information, various methods evolve every now and then like mushroom to crack and crash the cryptographic systems. NSA-approved Data Encryption Standard published in 1977 gained quick worldwide adoption.

  • Fast Correlation Attacks: Methods and Countermeasures
    Fast Correlation Attacks: Methods and Countermeasures Willi Meier FHNW, Switzerland Abstract. Fast correlation attacks have considerably evolved since their first appearance. They have lead to new design criteria of stream ciphers, and have found applications in other areas of communications and cryp- tography. In this paper, a review of the development of fast correlation attacks and their implications on the design of stream ciphers over the past two decades is given. Keywords: stream cipher, cryptanalysis, correlation attack. 1 Introduction In recent years, much effort has been put into a better understanding of the design and security of stream ciphers. Stream ciphers have been designed to be efficient either in constrained hardware or to have high efficiency in software. A synchronous stream cipher generates a pseudorandom sequence, the keystream, by a finite state machine whose initial state is determined as a function of the secret key and a public variable, the initialization vector. In an additive stream cipher, the ciphertext is obtained by bitwise addition of the keystream to the plaintext. We focus here on stream ciphers that are designed using simple devices like linear feedback shift registers (LFSRs). Such designs have been the main tar- get of correlation attacks. LFSRs are easy to implement and run efficiently in hardware. However such devices produce predictable output, and cannot be used directly for cryptographic applications. A common method aiming at destroy- ing the predictability of the output of such devices is to use their output as input of suitably designed non-linear functions that produce the keystream. As the attacks to be described later show, care has to be taken in the choice of these functions.

It is suitable for using in the cases of massive data transfer or resource constraints, and has always been a hot and central research topic in cryptography. With the rapid development of network and communication technology, cipher algorithms play more and more crucial role in information security. Simultaneously, the application environment of cipher algorithms is in- creasingly complex, which challenges the existing cipher algorithms and calls for novel suitable designs. To accommodate new strict requirements and provide systematic scientific basis for future designs, this paper reviews the development history of stream ciphers, classifies and summarizes the design principles of typical stream ciphers in groups, briefly discusses the advantages and weakness of various stream ciphers in terms of security and implementation. Finally, it tries to foresee the prospective design directions of stream ciphers.

  • Higher Order Correlation Attacks, XL Algorithm and Cryptanalysis of Toyocrypt
    Higher Order Correlation Attacks, XL Algorithm and Cryptanalysis of Toyocrypt Nicolas T. Courtois Cryptography research, Schlumberger Smart Cards, 36-38 rue de la Princesse, BP 45, 78430 Louveciennes Cedex, France http://www.nicolascourtois.net [email protected] Abstract. Many stream ciphers are built of a linear sequence generator and a non-linear output function f. There is an abundant literature on (fast) correlation attacks, that use linear approximations of f to attack the cipher. In this paper we explore higher degree approximations, much less studied. We reduce the cryptanalysis of a stream cipher to solv- ing a system of multivariate equations that is overdefined (much more equations than unknowns). We adapt the XL method, introduced at Eurocrypt 2000 for overdefined quadratic systems, to solving equations of higher degree. Though the exact complexity of XL remains an open problem, there is no doubt that it works perfectly well for such largely overdefined systems as ours, and we confirm this by computer simula- tions. We show that using XL, it is possible to break stream ciphers that were known to be immune to all previously known attacks. For exam- ple, we cryptanalyse the stream cipher Toyocrypt accepted to the second phase of the Japanese government Cryptrec program. Our best attack on Toyocrypt takes 292 CPU clocks for a 128-bit cipher. The interesting feature of our XL-based higher degree correlation attacks is, their very loose requirements on the known keystream needed. For example they may work knowing ONLY that the ciphertext is in English. Key Words: Algebraic cryptanalysis, multivariate equations, overde- fined equations, Reed-Muller codes, correlation immunity, XL algorithm, Gr¨obner bases, stream ciphers, pseudo-random generators, nonlinear fil- tering, ciphertext-only attacks, Toyocrypt, Cryptrec.

  • Applications of Search Techniques to Cryptanalysis and the Construction of Cipher Components. James David Mclaughlin Submitted F
    Applications of search techniques to cryptanalysis and the construction of cipher components. James David McLaughlin Submitted for the degree of Doctor of Philosophy (PhD) University of York Department of Computer Science September 2012 2 Abstract In this dissertation, we investigate the ways in which search techniques, and in particular metaheuristic search techniques, can be used in cryptology. We address the design of simple cryptographic components (Boolean functions), before moving on to more complex entities (S-boxes). The emphasis then shifts from the construction of cryptographic arte- facts to the related area of cryptanalysis, in which we first derive non-linear approximations to S-boxes more powerful than the existing linear approximations, and then exploit these in cryptanalytic attacks against the ciphers DES and Serpent.

  • Affine-Power S-Boxes Over Galois Fields with Area-Optimized Logic Implementations
    Affine-Power S-Boxes over Galois Fields with Area-Optimized Logic Implementations Christopher A. Wood12, Stanis law P. Radziszowski2, Marcin Lukowiak3 1 Department of Computer Science, UC Irvine 2 Department of Computer Science, Rochester Institute of Technology 3 Department of Computer Engineering, Rochester Institute of Technology Abstract. Cryptographic S-boxes are fundamental in key-iterated sub- stitution permutation network (SPN) designs for block ciphers. As a natural way for realizing Shannon's confusion and diffusion properties in cryptographic primitives through nonlinear and linear behavior, re- spectively, SPN designs served as the basis for the Advanced Encryption Standard and a variety of other block ciphers. In this work we present a methodology for minimizing the logic resources for n-bit affine-power S- boxes over Galois fields based on measurable security properties and find- ing corresponding area-efficient combinational implementations in hard- ware. Motivated by the potential need for new and larger S-boxes, we use our methodology to find area-optimized circuits for 8- and 16-bit S-boxes. Our methodology is capable of finding good upper bounds on the number of XOR and AND gate equivalents needed for these circuits, which can be further optimized using modern CAD tools. Keywords: S-box design and construction, 16-bit S-boxes, composite Galois fields, S-box combinational circuits 1 Introduction In order to enable area-efficient hardware implementations of block ci- phers based on the key-iterated substitution permutation network (SPN) design principle, such as the Advanced Encryption Standard (AES) [13], the logic resources for each component or operation in the algorithm must be reduced as much as feasible.
