A New Method for Impossible Differential Cryptanalysis of 8-Round Advanced Encryption Standard

This paper first presents an impossible differential property for 5-round Advanced Encryption Standard （AES） with high probability. Based on the property and the impossible differential cryptanalytic method for the 5-round AES, a new method is proposed for cryptanalyzing the 8-round AES-192 and AES-256. This attack on the reduced 8-round AES-192 demands 2^121 words of memory, and performs 2^148 8-round AES-192 encryptions. This attack on the reduced 8-round AES-256 demands 2^153 words of memory, and performs 2^180 8-round AES-256 encryptions. Furthermore, both AES-192 and AES-256 require about 2^98 chosen plaintexts for this attack, and have the same probability that is only 2^-3 to fail to recover the secret key.

Ambiguous Cylinders: a New Class of Impossible Objects

This paper presents a new class of surfaces that give two quite different appearances when they are seen from two special viewpoints. The inconsistent appearances can be perceived by simultaneously viewing them directly and in a mirror. This phenomenon is a new type of optical illusion, and we have named it the ＂ambiguous cylinder illusion＂, because it is typically generated by cylindrical surfaces. We consider why this illusion arises, and we present a mathematical method for designing ambiguous cylinders.

Non-Existence of One-Byte Active Impossible Differentials for 5-Round AES in the Master-Key Setting

Impossible differential cryptanalysis is an important approach to evaluate the security of block ciphers. In EUROCRYPT 2016, Sun, et al. proved that there exists no impossible differential longer than four rounds for the AES structure where S-boxes are arbitrary. In DCC 2019, Wang,et al. proved that any differential is possible for 5-round AES, assuming that the round keys are independent and uniformly random. In ASIACRYPT 2020, Hu, et al. used automatic search to show that there exists no one-byte active impossible differential for 5-round AES-128 considering the relations of 3-round keys. By algebraic methods, this paper theoretically proves that there exists no one-byte active impossible differential for 5-round AES even considering the relations of all round keys. Firstly,the authors prove the independence of ten bytes in the consecutive four round keys under the key schedule of AES-128. Then 5-round AES is decomposed to three subfunctions and the propagations of the considered differences in these subfunctions are discussed. Finally, the authors prove that the considered differential trails can be connected by the ten bytes of round keys. Furthermore, for any given one-byte active differential, there are at least 2^(51) master keys such that the differential is possible for 5-round AES-128.

Theoretical Framework for a Polymorphic Network Environment

The question of whether an ideal network exists with global scalability in its full life cycle has always been a first-principles problem in the research of network systems and architectures.Thus far,it has not been possible to scientifically practice the design criteria of an ideal network in a unimorphic network system,making it difficult to adapt to known services with clear application scenarios while supporting the ever-growing future services with unexpected characteristics.Here,we theoretically prove that no unimorphic network system can simultaneously meet the scalability requirement in a full cycle in three dimensions—the service-level agreement(S),multiplexity(M),and variousness(V)—which we name as the“impossible SMV triangle”dilemma.It is only by transforming the current network development paradigm that the contradiction between global scalability and a unified network infrastructure can be resolved from the perspectives of thinking,methodology,and practice norms.In this paper,we propose a theoretical framework called the polymorphic network environment(PNE),the first principle of which is to separate or decouple application network systems from the infrastructure environment and,under the given resource conditions,use core technologies such as the elementization of network baselines,the dynamic aggregation of resources,and collaborative software and hardware arrangements to generate the capability of the“network of networks.”This makes it possible to construct an ideal network system that is designed for change and capable of symbiosis and coexistence with the generative network morpha in the spatiotemporal dimensions.An environment test for principle verification shows that the generated representative application network modalities can not only coexist without mutual influence but also independently match well-defined multimedia services or custom services under the constraints of technical and economic indicators.

Searching for impossible subspace trails and improved impossible differential characteristics for SIMON-like block ciphers

In this paper,we greatly increase the number of impossible differentials for SIMON and SIMECK by eliminating the 1-bit constraint in input/output difference,which is the precondition to ameliorate the complexity of attacks.We propose an algorithm which can greatly reduce the searching complexity to find such trails efficiently since the search space exponentially expands to find impossible differentials with multiple active bits.There is another situation leading to the contradiction in impossible differentials except for miss-in-the-middle.We show how the contradiction happens and conclude the precondition of it defined as miss-from-the-middle.It makes our results more comprehensive by applying these two approach simultaneously.This paper gives for the first time impossible differential characteristics with multiple active bits for SIMON and SIMECK,leading to a great increase in the number.The results can be verified not only by covering the state-of-art,but also by the MILP model.

Impossible Differential Cryptanalysis of Reduced-Round ARIA and Camellia

This paper studies the security of the block ciphers ARIA and Camellia against impossible differential cryptanalysis. Our work improves the best impossible differential cryptanalysis of ARIA and Camellia known so far. The designers of ARIA expected no impossible differentials exist for 4-round ARIA. However, we found some nontrivial 4-round impossible differentials, which may lead to a possible attack on 6-round ARIA. Moreover, we found some nontrivial 8-round impossible differentials for Camellia, whereas only 7-round impossible differentials were previously known. By using the 8-round impossible differentials, we presented an attack on 12-round Camellia without FL/FL^-1 layers.

Impossible Differential Attacks on 13-Round CLEFIA-128

CLEFIA, a new 128-bit block cipher proposed by Sony Corporation, is increasingly attracting cryptanalysts＇ attention. In this paper, we present two new impossible differential attacks on 13 rounds of CLEFIA-128. The proposed attacks utilize a variety of previously known techniques, in particular the hash table technique and redundancy in the key schedule of this block cipher. The first attack does not consider the whitening layers of CLEFIA, requires 21~9＂5 chosen plaintexts, and has a running time equivalent to about 2112.9 encryptions. The second attack preserves the whitening layers, requires 2117.8 chosen plaintexts, and has a total time complexity equivalent to about 2121.2 encryptions.

Related-Key Impossible Diferential Attack on Reduced-Round LBlock

LBlock is a 32-round lightweight block cipher with 64-bit block size and 80-bit key. This paper identifies 16- round related-key impossible differentials of LBlock, which are better than the 15-round related-key impossible differentials used in the previous attack. Based on these 16-round related-key impossible differentials, we can attack 23 rounds of LBlock while the previous related-key impossible differential attacks could only work on 22-round LBlock. This makes our attack on LBlock the best attack in terms of the number of attacked rounds.

Impossible differential cryptanalysis of advanced encryption standard

Impossible differential cryptanalysis is a method recovering secret key, which gets rid of the keys that satisfy impossible differential relations. This paper concentrates on the impossible differential cryptanalysis of Advanced Encryption Standard （AES） and presents two methods for impossible differential cryptanalysis of 7-round AES-192 and 8-round AES-256 combined with time-memory trade-off by exploiting weaknesses in their key schedule. This attack on the reduced to 7-round AES-192 requires about 294.5 chosen plaintexts, demands 2129 words of memory, and performs 2157 7-round AES-192 encryptions. Furthermore, this attack on the reduced to 8-round AES-256 requires about 2^101 chosen plaintexts, demands 2^201 words of memory, and performs 2^228 8-round AES-256 encryptions.

英语形容词句型

在英语中,形容词用在某些联系动词(主要是be,become,seem等)之后,常常还需要一定形式的补充成份。需要何种形式的补充成份,主要与形容词有关。Hornby称这种形容词及其补充成份为“形容词句型”(Adjective Patterns)。形容词句型主要有以下三个: Ⅰ.形容词+to-不定式Ⅱ.形容词+介词短语Ⅲ.形容词+从语形容词用于哪个句型有一定的习惯,例如,有些形容词之后只接介词短语,不接to-不定式。

quite与very

quite 与 very 是英语中使用频率较高的两个副词,均表示“非常”之意,但其差异微妙,用法繁杂,因此有必要作一比较来发现规律,以便掌握。1.没有等级之分的形容词,如 perfect(完美的),impossible(不可能的),dead(死的),right(正确的),wrong(错误的),full(满的),empty(空的),sure(确信的),certain(肯定的)。

The Possibility of Semantic Features and Analysis of Figures of Speech —— Cognitive Figures and Expressive Figures

In this paper, linguistic methodology is suggested for approaching figures of speech formed due to shift of cognitive relations. First, requisite features, possible features and impossible features are proposed on the basis of semantic analysis and their interrelationships and expressions are discussed. Then it is further argued that all figures formed due to shift of cognitive relation are expressed to accept an impossible feature; and there are four semantic forms to accept it: “zero distance/distanced”, “implicit/explicit”, “direct/indirect”, “positive/negative”. Finally, starting from the two approaches to figures we comment on the traditional idea of separating decoration and substance and the new idea of “function as form”.
