  • Predicting the elliptic curve congruential generator
    • Authors: László Mérai
      Pages: 193 - 203
      Abstract: Let p be a prime and let \(\mathbf {E}\) be an elliptic curve defined over the finite field \(\mathbb {F}_p\) of p elements. For a point \(G\in \mathbf {E}(\mathbb {F}_p)\) the elliptic curve congruential generator (with respect to the first coordinate) is a sequence \((x_n)\) defined by the relation \(x_n=x(W_n)=x(W_{n-1}\oplus G)=x(nG\oplus W_0)\) , \(n=1,2,\ldots \) , where \(\oplus \) denotes the group operation in \(\mathbf {E}\) and \(W_0\) is an initial point. In this paper, we show that if some consecutive elements of the sequence \((x_n)\) are given as integers, then one can compute in polynomial time an elliptic curve congruential generator (where the curve possibly defined over the rationals or over a residue ring) such that the generated sequence is identical to \((x_n)\) in the revealed segment. It turns out that in practice, all the secret parameters, and thus the whole sequence \((x_n)\) , can be computed from eight consecutive elements, even if the prime and the elliptic curve are private.

  • On the dynamics of endomorphisms of finite groups
    • Authors: Alexander Bors
      Pages: 205 - 214
      Abstract: Aiming at a better understanding of finite groups as finite dynamical systems, we show that by a version of Fitting’s Lemma for groups, each state space of an endomorphism of a finite group is a graph tensor product of a finite directed 1-tree whose cycle is a loop with a disjoint union of cycles, generalizing results of Hernández-Toledo on linear finite dynamical systems, and we fully characterize the possible forms of state spaces of nilpotent endomorphisms via their “ramification behavior”. Finally, as an application, we will count the isomorphism types of state spaces of endomorphisms of finite cyclic groups in general, extending results of Hernández-Toledo on primary cyclic groups of odd order.

  • More classes of permutation polynomials of the form $$(x^{p^m}-x+\delta
           )^s+L(x)$$ ( x p m - x + δ ) s + L ( x )
    • Authors: Dabin Zheng; Zhen Chen
      Pages: 215 - 223
      Abstract: This note presents two classes of permutation polynomials of the form \((x^{p^m}-x+\delta )^s+L(x)\) over the finite fields \({{\mathbb {F}}}_{p^{2m}}\) as a supplement of the recent works of Zha, Hu and Li, Helleseth and Tang.

  • An automatic semigroup of languages
    • Authors: B. Panbehkar; H. Doostie
      Pages: 225 - 235
      Abstract: For a finitely generated automatic semigroup \(S=\langle A\rangle \) we define a semigroup \(L_S\) of languages concerning the automatic structure of S, and study the automaticity of \(L_S\) . Also we investigate the natural question “when S is isomorphic to \(L_S\) ?”. Finally, we attempt to verify the equation \(L_S\cup L_T=L_{S\cup T}\) for two non-monoid semigroups \((S, *)\) and (T, o).

  • Affine equivalence and non-linearity of permutations over $$\mathbb Z_n$$
           Z n
    • Authors: Yogesh Kumar; P. R. Mishra; N. Rajesh Pillai; R. K. Sharma
      Pages: 257 - 279
      Abstract: In this paper, we explore further the non-linearity and affine equivalence as proposed by Mishra et al. (Non-linearity and affine equivalence of permutations. 2014. http://eprint.iacr.org/2014/974.pdf). We propose an efficient algorithm in order to compute affine equivalent permutation(s) of a given permutation of length n, of complexity \(O(n^4)\) in worst case and \(O(n^2)\) in best case. Also in the affirmative in a special case \(n = p\) , prime, it is of complexity \(O(n^3)\) . We also propose an upper bound of non-linearity of permutation(s) whose length satisfies a special condition. Further, behaviour of non-linearity on direct sum and skew sum of permutation has been analysed. Also the distance of an affine permutation from the other affine permutations has also been studied. The cryptographic implication of this work is on permutation based stream ciphers like RC4 and its variants. In this paper, we have applied this study on RC4 cipher. The analysis shows that increasing the key size for RC4 does not mean that increase in the security or saturation after a limit but security may falls as key size increases.

  • Cryptanalysis of a key exchange protocol based on the ring $$E_p^{(m)}$$ E
           p ( m )
    • Authors: Yang Zhang
      Abstract: An extension of Bergman’s ring (Israel J Math 18:257–277, 1974) was introduced by Climent et al. (Appl Algebra Eng Commun Comput 23:347–361, 2014). For this ring called \(E_p^{(m)}\) , they established that only a negligible fraction of elements are invertible, and then proposed a key exchange protocol based on this property. Shortly afterwards, they constructed another key agreement protocol for multicast over this ring (WIT Trans Inf Commun Technol 45:13–24, 2013). In this paper, we introduce a polynomial-time attack to these two protocols without using invertible elements.

  • Verifiability-based conversion from CPA to CCA-secure predicate encryption
    • Authors: Mridul Nandi; Tapas Pandit
      Abstract: Predicate encryption (PE), a generalization of attribute-based encryption (ABE), is a versatile tool for providing access control over data. The underlying predicate for a PE is parametrized by an index, called system parameter or simply system-index. A system-index, in general, consists of component(s) from \(\mathbb {N}\) . Yamada et al. in PKC 2011 proposed a verifiability-based conversion from CPA to CCA-secure ABE. This conversion was generalized by Yamada et al. in PKC 2012 from ABE to PE. In the later conversion, the authors considered the system-index to be a single component. In practice, there are many schemes, e.g., functional encryption for general relations and hierarchical-inner product (HIP) encryption schemes of Okamoto-Takashima in CRYPTO 2010, CANS 2011 and EUROCRYPT 2012, where system-indices consist of more than a single component. Therefore, for these schemes, the conversion of Yamada et al. (in PKC, 2012) is out of scope. In this paper, we revisit the CPA to CCA conversion for PE and propose a new conversion based on verifiability. The proposed conversion works irrespective of the number of components in the system-indices. It generalizes the existing conversion of Yamada et al. (in PKC, 2011) from ABE to PE. The PE schemes which are realized by the conversion of Yamada et al. (2011) are also realized by our conversion. Therefore, the conversion of ours has more scope than the conversion proposed in 2012. We show that all the aforementioned CPA-secure schemes for general relations and HIP relation are easily converted to the corresponding CCA-secure schemes by our conversion. Further, we show a generic conversion from CPA to CCA-secure functional encryption for regular languages which captures the existing PE schemes for regular languages.

  • A pseudorandom number generator based on worst-case lattice problems
    • Authors: Pierre-Louis Cayrel; Mohammed Meziani; Ousmane Ndiaye; Richard Lindner; Rosemberg Silva
      Abstract: In this paper we construct a pseudorandom number generator using only worst-case hardness assumptions for standard lattice problems. With a common technique, we can then build a stream cipher by combining the generated pseudorandom sequence with the plaintext. Moreover, as an option to gain efficiency both in terms of speed and memory, we suggest the use of ideal lattices in the construction. Currently, there is no known attack that could exploit this choice. Our implementation for Graphics Processing Units leverages from the parallelism inherent in lattice schemes and reaches performances comparable to the fastest known constructions that enjoy security proofs.

  • Weight enumerators of a class of linear codes
    • Authors: Jaehyun Ahn; Dongseok Ka
      Abstract: Recently, linear codes constructed from defining sets have been studied widely and they have many applications. For an odd prime p, let \(q=p^{m}\) for a positive integer m and \(\mathrm {Tr}_{m}\) the trace function from \(\mathbb {F}_{q}\) onto \(\mathbb {F}_{p}\) . In this paper, for a positive integer t, let \(D\subset \mathbb {F}^{t}_{q}\) and \(D=\{(x_{1},x_{2}) \in (\mathbb {F}_{q}^{*})^{2} : \mathrm {Tr}_{m}(x_{1}+x_{2})=0\}\) , we define a p-ary linear code \(\mathcal {C}_{D}\) by $$\begin{aligned} \mathcal {C}_{D}=\left\{ \mathbf {c}(a_{1},a_{2}) : (a_{1},a_{2})\in \mathbb {F}^{2}_{q}\right\} , \end{aligned}$$ where $$\begin{aligned} \mathbf {c}(a_{1},a_{2})=\left( \mathrm {Tr}_{m}\left( a_{1}x^{2}_{1}+a_{2}x^{2}_{2}\right) \right) _{(x_{1},x_{2})\in D}. \end{aligned}$$ We compute the weight enumerators of the punctured codes \(\mathcal {C}_{D}\) .

  • The l -th power Diffie–Hellman problem and the l -th root
           Diffie–Hellman problem
    • Authors: Dongyoung Roh; I-Yeol Kim; Sang Geun Hahn
      Abstract: There are many variants of the computational Diffie–Hellman problem that are necessary to provide security of many cryptographic schemes. Two of them are the square Diffie–Hellman problem and the square root Diffie–Hellman problem. Recently, the first and third authors proved that these two problems are polynomial-time equivalent under a certain condition (Roh and Hahn in Des Codes Cryptogr 62(2):179–187, 2011). In this paper, we generalize this result. We introduce the l-th power Diffie–Hellman problem and the l-th root Diffie–Hellman problem and show that these two problems are polynomial-time equivalent for \(l = O (\log p)\) under a condition similar to that of Roh and Hahn (2011), where p is the order of the underlying group.

           -constacyclic codes over $${\mathbb {F}}_{3^m}[u]/\langle u^4\rangle $$ F
           3 m [ u ] / ⟨ u 4 ⟩ of length 3 n
    • Authors: Yuan Cao; Yonglin Cao; Li Dong
      Abstract: Let \({\mathbb {F}}_{3^m}\) be a finite field of cardinality \(3^m\) , \(R={\mathbb {F}}_{3^m}[u]/\langle u^4\rangle \) which is a finite chain ring, and n be a positive integer satisfying \(\mathrm{gcd}(3,n)=1\) . For any \(\delta ,\alpha \in {\mathbb {F}}_{3^m}^{\times }\) , an explicit representation for all distinct \((\delta +\alpha u^2)\) -constacyclic codes over R of length 3n is given, formulas for the number of all such codes and the number of codewords in each code are provided, respectively. Moreover, the dual code for each of these codes is determined explicitly.

  • Mirror theory and cryptography
    • Authors: Jacques Patarin
      Abstract: “Mirror Theory” is the theory that evaluates the number of solutions of affine systems of equalities \(({=})\) and non equalities ( \(\ne \) ) in finite groups. It is deeply related to the security and attacks of many generic cryptographic secret key schemes, for example random Feistel schemes (balanced or unbalanced), Misty schemes, Xor of two pseudo-random bijections to generate a pseudo-random function etc. In this paper we will assume that the groups are abelian. Most of time in cryptography the group is \(((\mathbb {Z}/2\mathbb {Z})^n, \oplus )\) and we will concentrate this paper on these cases. We will present here general definitions, some theorems, and many examples and computer simulations.

  • New binary linear codes from quasi-cyclic codes and an augmentation
           algorithm
    • Authors: Nuh Aydin; Nicholas Connolly; John Murphree
      Abstract: Explicit construction of linear codes with best possible parameters is one of the major problems in coding theory. Among all alphabets of interest, the binary alphabet is the most important one. In this work we use a comprehensive search strategy to find new binary linear codes in the well-known and intensively studied class of quasi-cyclic (QC) codes. We also introduce a generalization of an augmentation algorithm to obtain further new codes from those QC codes. Also applying the standard methods of obtaining new codes from existing codes, such as puncturing, extending and shortening, we have found a total of 62 new binary linear codes.

  • A class of primitive BCH codes and their weight distribution
    • Authors: Haode Yan
      Abstract: BCH codes, as a special subclass of cyclic codes, are in most cases among the best cyclic codes. Recently, several classes of BCH codes with length \(n=q^m-1\) and designed distances \(\delta =(q-1)q^{m-1}-1-q^{\lfloor (m-1)/2\rfloor }\) and \(\delta =(q-1)q^{m-1}-1-q^{\lfloor (m+1)/2\rfloor }\) were widely studied, where \(m\ge 4\) is an integer. In this paper, we consider the case \(m=3\) . The weight distribution of a class of primitive BCH codes with designed distance \(q^3-q^2-q-2\) is determined, which solves an open problem put forward in Ding et al. (Finite Fields Appl 45:237–263, 2017).

  • Linear codes from quadratic forms
    • Authors: Xiaoni Du; Yunqi Wan
      Abstract: Linear codes have been an interesting topic in both theory and practice for many years. In this paper, for an odd prime power q, we present a class of linear codes over finite fields \(F_q\) with quadratic forms via a general construction and then determine the explicit complete weight enumerators of these linear codes. Our construction covers some related ones via quadratic form functions and the linear codes may have applications in cryptography and secret sharing schemes.
