  • Integral Cryptanalysis on Full MISTY1⋆
    Integral Cryptanalysis on Full MISTY1? Yosuke Todo NTT Secure Platform Laboratories, Tokyo, Japan [email protected] Abstract. MISTY1 is a block cipher designed by Matsui in 1997. It was well evaluated and standardized by projects, such as CRYPTREC, ISO/IEC, and NESSIE. In this paper, we propose a key recovery attack on the full MISTY1, i.e., we show that 8-round MISTY1 with 5 FL layers does not have 128-bit security. Many attacks against MISTY1 have been proposed, but there is no attack against the full MISTY1. Therefore, our attack is the first cryptanalysis against the full MISTY1. We construct a new integral characteristic by using the propagation characteristic of the division property, which was proposed in 2015. We first improve the division property by optimizing a public S-box and then construct a 6-round integral characteristic on MISTY1. Finally, we recover the secret key of the full MISTY1 with 263:58 chosen plaintexts and 2121 time complexity. Moreover, if we can use 263:994 chosen plaintexts, the time complexity for our attack is reduced to 2107:9. Note that our cryptanalysis is a theoretical attack. Therefore, the practical use of MISTY1 will not be affected by our attack. Keywords: MISTY1, Integral attack, Division property 1 Introduction MISTY [Mat97] is a block cipher designed by Matsui in 1997 and is based on the theory of provable security [Nyb94,NK95] against differential attack [BS90] and linear attack [Mat93]. MISTY has a recursive structure, and the component function has a unique structure, the so-called MISTY structure [Mat96].

  • New Security Proofs for the 3GPP Confidentiality and Integrity
    An extended abstract of this paper appears in Fast Software Encryption, FSE 2004, Lecture Notes in Computer Science, W. Meier and B. Roy editors, Springer-Verlag, 2004. This is the full version. New Security Proofs for the 3GPP Confidentiality and Integrity Algorithms Tetsu Iwata¤ Tadayoshi Kohnoy January 26, 2004 Abstract This paper analyses the 3GPP confidentiality and integrity schemes adopted by Universal Mobile Telecommunication System, an emerging standard for third generation wireless commu- nications. The schemes, known as f8 and f9, are based on the block cipher KASUMI. Although previous works claim security proofs for f8 and f90, where f90 is a generalized versions of f9, it was recently shown that these proofs are incorrect. Moreover, Iwata and Kurosawa (2003) showed that it is impossible to prove f8 and f90 secure under the standard PRP assumption on the underlying block cipher. We address this issue here, showing that it is possible to prove f80 and f90 secure if we make the assumption that the underlying block cipher is a secure PRP-RKA against a certain class of related-key attacks; here f80 is a generalized version of f8. Our results clarify the assumptions necessary in order for f8 and f9 to be secure and, since no related-key attacks are known against the full eight rounds of KASUMI, lead us to believe that the confidentiality and integrity mechanisms used in real 3GPP applications are secure.

  • Known and Chosen Key Differential Distinguishers for Block Ciphers
    Known and Chosen Key Differential Distinguishers for Block Ciphers Ivica Nikoli´c1?, Josef Pieprzyk2, Przemys law Soko lowski2;3, Ron Steinfeld2 1 University of Luxembourg, Luxembourg 2 Macquarie University, Australia 3 Adam Mickiewicz University, Poland [email protected], [email protected], [email protected], [email protected] Abstract. In this paper we investigate the differential properties of block ciphers in hash function modes of operation. First we show the impact of differential trails for block ciphers on collision attacks for various hash function constructions based on block ciphers. Further, we prove the lower bound for finding a pair that follows some truncated differential in case of a random permutation. Then we present open-key differential distinguishers for some well known round-reduced block ciphers. Keywords: Block cipher, differential attack, open-key distinguisher, Crypton, Hierocrypt, SAFER++, Square. 1 Introduction Block ciphers play an important role in symmetric cryptography providing the basic tool for encryp- tion. They are the oldest and most scrutinized cryptographic tool. Consequently, they are the most trusted cryptographic algorithms that are often used as the underlying tool to construct other cryp- tographic algorithms. One such application of block ciphers is for building compression functions for the hash functions. There are many constructions (also called hash function modes) for turning a block cipher into a compression function. Probably the most popular is the well-known Davies-Meyer mode. Preneel et al. in [27] have considered all possible modes that can be defined for a single application of n-bit block cipher in order to produce an n-bit compression function.

  • Differential-Linear Crypt Analysis
    Differential-Linear Crypt analysis Susan K. Langfordl and Martin E. Hellman Department of Electrical Engineering Stanford University Stanford, CA 94035-4055 Abstract. This paper introduces a new chosen text attack on iterated cryptosystems, such as the Data Encryption Standard (DES). The attack is very efficient for 8-round DES,2 recovering 10 bits of key with 80% probability of success using only 512 chosen plaintexts. The probability of success increases to 95% using 768 chosen plaintexts. More key can be recovered with reduced probability of success. The attack takes less than 10 seconds on a SUN-4 workstation. While comparable in speed to existing attacks, this 8-round attack represents an order of magnitude improvement in the amount of required text. 1 Summary Iterated cryptosystems are encryption algorithms created by repeating a simple encryption function n times. Each iteration, or round, is a function of the previ- ous round’s oulpul and the key. Probably the best known algorithm of this type is the Data Encryption Standard (DES) [6].Because DES is widely used, it has been the focus of much of the research on the strength of iterated cryptosystems and is the system used as the sole example in this paper. Three major attacks on DES are exhaustive search [2, 71, Biham-Shamir’s differential cryptanalysis [l], and Matsui’s linear cryptanalysis [3, 4, 51. While exhaustive search is still the most practical attack for full 16 round DES, re- search interest is focused on the latter analytic attacks, in the hope or fear that improvements will render them practical as well.

  • Miss in the Middle Attacks on IDEA and Khufu
    Miss in the Middle Attacks on IDEA and Khufu Eli Biham? Alex Biryukov?? Adi Shamir??? Abstract. In a recent paper we developed a new cryptanalytic techni- que based on impossible differentials, and used it to attack the Skipjack encryption algorithm reduced from 32 to 31 rounds. In this paper we describe the application of this technique to the block ciphers IDEA and Khufu. In both cases the new attacks cover more rounds than the best currently known attacks. This demonstrates the power of the new cryptanalytic technique, shows that it is applicable to a larger class of cryptosystems, and develops new technical tools for applying it in new situations. 1 Introduction In [5,17] a new cryptanalytic technique based on impossible differentials was proposed, and its application to Skipjack [28] and DEAL [17] was described. In this paper we apply this technique to the IDEA and Khufu cryptosystems. Our new attacks are much more efficient and cover more rounds than the best previously known attacks on these ciphers. The main idea behind these new attacks is a bit counter-intuitive. Unlike tra- ditional differential and linear cryptanalysis which predict and detect statistical events of highest possible probability, our new approach is to search for events that never happen. Such impossible events are then used to distinguish the ci- pher from a random permutation, or to perform key elimination (a candidate key is obviously wrong if it leads to an impossible event). The fact that impossible events can be useful in cryptanalysis is an old idea (for example, some of the attacks on Enigma were based on the observation that letters can not be encrypted to themselves).

  • Improbable Differential from Impossible Differential
    Improbable Differential from Impossible Differential: On the Validity of the Model C´elineBlondeau Aalto University, School of Science, Department of Information and Computer Science [email protected] Abstract. Differentials with low probability are used in improbable dif- ferential cryptanalysis to distinguish a cipher from a random permuta- tion. Due to large diffusion, finding such differentials for actual ciphers re- mains a challenging task. At Indocrypt 2010, Tezcan proposed a method to derive improbable differential distinguishers from impossible differ- ential ones. In this paper, we discuss the validity of the assumptions made in the computation of the improbable differential probabilities. In particular, we show based on experiments that such improbable differ- ential cryptanalysis can fail. The validity of the improbable differential cryptanalyses on PRESENT and CLEFIA is discussed. Keywords:improbable differential, impossible differential, truncated differential, PRESENT, CLEFIA 1 Introduction Since the introduction of differential cryptanalysis [2] in the beginning of the 90's, many generalizations of this attack have been proposed to cryptanalyse a large number of block ciphers. While most of them exploit differentials with high probability, in the impossible differential cryptanalysis context [1] attackers take advantage of zero-probability differentials. Recently a variation of this attack called improbable differential cryptanalysis have been introduced by Tezcan [21] at Indocrypt 2010 and by Mala, Dakhilalian and Shakiba [15]. In this context, differentials with low probabilities are used to distinguish the cipher from a random permutation. While in theory this attack could be efficient on some ciphers, in practice, it may be hard to find differentials or truncated differentials with such small prob- abilities.

  • Pseudorandomness of Basic Structures in the Block Cipher KASUMI
    Pseudorandomness of Basic Structures in the Block Cipher KASUMI Ju-Sung Kang, Bart Preneel, Heuisu Ryu, Kyo Il Chung, and Chee Hang Park The notion of pseudorandomness is the theoretical I. INTRODUCTION foundation on which to consider the soundness of a basic structure used in some block ciphers. We examine the A block cipher is a family of permutations on a message pseudorandomness of the block cipher KASUMI, which space indexed by a secret key. Luby and Rackoff [1] will be used in the next-generation cellular phones. First, we introduced a theoretical model for the security of block ciphers prove that the four-round unbalanced MISTY-type by using the notion of pseudorandom and super-pseudorandom transformation is pseudorandom in order to illustrate the permutations. A pseudorandom permutation can be interpreted pseudorandomness of the inside round function FI of as a block cipher that cannot be distinguished from a truly KASUMI under an adaptive distinguisher model. Second, random permutation regardless of how many polynomial we show that the three-round KASUMI-like structure is not encryption queries an attacker makes. A super-pseudorandom pseudorandom but the four-round KASUMI-like structure permutation can be interpreted as a block cipher that cannot be is pseudorandom under a non-adaptive distinguisher model. distinguished from a truly random permutation regardless of how many polynomial encryption and decryption queries an attacker makes. Luby and Rackoff used a Feistel-type transformation defined by the typical two-block structure of the block cipher DES in order to construct pseudorandom and super-pseudorandom permutations from pseudorandom functions [1].

  • Differential-Linear Cryptanalysis Revisited
    Differential-Linear Cryptanalysis Revisited C´elineBlondeau1 and Gregor Leander2 and Kaisa Nyberg1 1 Department of Information and Computer Science, Aalto University School of Science, Finland fceline.blondeau, [email protected] 2 Faculty of Electrical Engineering and Information Technology, Ruhr Universit¨atBochum, Germany [email protected] Abstract. Block ciphers are arguably the most widely used type of cryptographic primitives. We are not able to assess the security of a block cipher as such, but only its security against known attacks. The two main classes of attacks are linear and differential attacks and their variants. While a fundamental link between differential and linear crypt- analysis was already given in 1994 by Chabaud and Vaudenay, these at- tacks have been studied independently. Only recently, in 2013 Blondeau and Nyberg used the link to compute the probability of a differential given the correlations of many linear approximations. On the cryptana- lytical side, differential and linear attacks have been applied on different parts of the cipher and then combined to one distinguisher over the ci- pher. This method is known since 1994 when Langford and Hellman presented the first differential-linear cryptanalysis of the DES. In this paper we take the natural step and apply the theoretical link between linear and differential cryptanalysis to differential-linear cryptanalysis to develop a concise theory of this method. We give an exact expression of the bias of a differential-linear approximation in a closed form under the sole assumption that the two parts of the cipher are independent. We also show how, under a clear assumption, to approximate the bias effi- ciently, and perform experiments on it.
