MaTRU‐KE revisited: CCA2‐secure key establishment protocol based on MaTRU

Sedat Akleylek, Nurşah Çevi̇k

International Journal of Communication Systems > 33 > 7 > n/a - n/a

Quantum attack–resistant cryptosystems are required for secure communication since there is a big demand to have quantum computers. Lattice‐based cryptography is one of the quantum‐secure families due to its key/ciphertext sizes and performance. NTRU‐based cryptosystems, a member of lattice‐based cryptosystems, have received much more attention. MaTRU, a noncommutative version of NTRU with some matrix...

BLSBA‐ED‐SSO: Bivariate Lévy‐stable bat algorithm‐based energy detection for spectrum sensing optimization in cognitive radio networks (CRNs)

Senthil Kumar Babu, C. Venkataramanan

International Journal of Communication Systems > 33 > 7 > n/a - n/a

The vacant licensed spectrum can be employed by the secondary users in cognitive radio networks. Nevertheless, this process of identification is frequently agreed with shadowing, multipath fading and receiver uncertainty problems. The primary contributions of the spectrum sensing techniques adopted in this work mainly concentrate on energy detection for spectrum sensing as well as to recognize the...

Vehicular HetNet load distribution using centralized control of software‐defined network

Debdatta Kandar, Babu Sena Paul, Phidahunlang Chyne

International Journal of Communication Systems > 33 > 7 > n/a - n/a

Current vehicular communication systems experience from nonflexible and costly devices, complicated control‐plane protocols, and vendor‐specific configuration interfaces. In the next generation vehicular communication, a mobile device (MD) will be installed on a car capable of accessing multiple services from different networks. So heterogeneous networks (HetNets) may play a vital role in vehicular...

An autonomic risk‐ and penalty‐aware resource allocation with probabilistic resource scaling mechanism for multilayer cloud resource provisioning

Arash Mazidi, Mehdi Golsorkhtabaramiri, Meisam Yadollahzadeh Tabari

International Journal of Communication Systems > 33 > 7 > n/a - n/a

Cloud computing environment allows presenting different services on the Internet in exchange for cost payment. Cloud providers can minimize their operational costs by auto‐scaling of the computational resources based on demand received from users. However, the time and cost required to increase and decrease the number of active computational resources are among the biggest limitations of scalability...

On the Herbrand functional interpretation

Paulo Oliva, Chuangjie Xu

Mathematical Logic Quarterly > 66 > 1 > 91 - 98

We show that the types of the witnesses in the Herbrand functional interpretation can be simplified, avoiding the use of “sets of functionals” in the interpretation of implication and universal quantification. This is done by presenting an alternative formulation of the Herbrand functional interpretation, which we show to be equivalent to the original presentation. As a result of this investigation...

Cohen forcing and inner models

Jonas Reitz

Mathematical Logic Quarterly > 66 > 1 > 65 - 72

Given an inner model

W \subset V

and a regular cardinal κ, we consider two alternatives for adding a subset to κ by forcing: the Cohen poset Add(κ, 1), and the Cohen poset of the inner model

Add {(κ, 1)}^{W}

. The forcing from W will be at least as strong as the forcing from V (in the sense that forcing with the former adds a generic for the latter) if and only if the two posets have the same cardinality. On the...

The torsion‐free part of the Ziegler spectrum of orders over Dedekind domains

Lorna Gregory, Sonia L'Innocente, Carlo Toffalori

Mathematical Logic Quarterly > 66 > 1 > 20 - 36

We study the R‐torsion‐free part of the Ziegler spectrum of an order Λ over a Dedekind domain R. We underline and comment on the role of lattices over Λ. We describe the torsion‐free part of the spectrum when Λ is of finite lattice representation type.

On p‐adic semi‐algebraic continuous selections

Athipat Thamrongthanyalak

Mathematical Logic Quarterly > 66 > 1 > 73 - 81

Let

E \subseteq Q_{p}^{n}

and T be a set‐valued map from E to

Q_{p}^{m}

. We prove that if T is p‐adic semi‐algebraic, lower semi‐continuous and

T (x)

is closed for every

x \in E

, then T has a p‐adic semi‐algebraic continuous selection. In addition, we include three applications of this result. The first one is related to Fefferman's and Kollár's question on existence of p‐adic semi‐algebraic continuous solution of linear equations...
