Impossible Differential Distinguishers of Two Generalized Feistel Structures
Security and Communication Networks, Volume 2020, Issue 1, 2020., 2020 Generalized Feistel structures are widely used in the design of block ciphers. In this paper, we focused on retrieving impossible differentials for two kinds of generalized Feistel structures: CAST256‐like structure with Substitution‐Permutation (SP) or Substitution‐Permutation‐Substitution (SPS) round functions (named CAST256SP and CAST256SPS ...

A Novel Approach to Communicate Secret Message Between Users Using Sponge Function Technique on NTRU [PDF]
, 2013 This paper presents a novel approach for a (key distribution) for secret message communication among a group (G). In order to increase security to distribute secret message (key), we introduce sponge functions using these at a specific permutation.

Evolutionary approach to secure mobile telecommunication networks [PDF]
, 2021 A series of encryption algorithms called A5 is used to secure mobile telephone communications, producing a pseudo-random sequence that will be exclusive OR (XORed) with the data flowing in the air interface in order to secure them.

Stream ciphers: A Practical Solution for Efficient Homomorphic-Ciphertext Compression [PDF]
, 2015 International audienceIn typical applications of homomorphic encryption, the first step consists for Alice to encrypt some plaintext m under Bob’s public key pk and to send the ciphertext c = HEpk(m) to some third-party evaluator Charlie.

Journal of Advanced Transportation, Volume 2018, Issue 1, 2018., 2018 Passive keyless entry and start system has been widely used in modern cars. Car owners can open the door or start the engine merely by having the key in their pocket. PKES was originally designed to establish a communication channel between the car and its key within approximately one meter.

Analysis of the Time Series Generated by a New High‐Dimensional Discrete Chaotic System
Complexity, Volume 2018, Issue 1, 2018., 2018 The chaotic behavior of low‐dimensional digital chaotic systems is seriously degraded, and the output sequence has a short period. In this study, a digital sequence generator based on a high‐dimensional chaotic system is proposed to ensure performance and security.

STP‐LWE: A Variant of Learning with Error for a Flexible Encryption
Mathematical Problems in Engineering, Volume 2014, Issue 1, 2014., 2014 We construct a flexible lattice based scheme based on semitensor product learning with errors (STP‐LWE), which is a variant of learning with errors problem. We have proved that STP‐LWE is hard when LWE is hard. Our scheme is proved to be secure against indistinguishable chosen message attacks, and it can achieve a balance between the security and ...

Low Power Built‐In Self‐Test Schemes for Array and Booth Multipliers
VLSI Design, Volume 12, Issue 3, Page 431-448, 2001., 2001 Recent trends in IC technology have given rise to a new requirement, that of low power dissipation during testing, that Built‐In Self‐Test (BIST) structures must target along with the traditional requirements. To this end, by exploiting the inherent properties of Carry Save, Carry Propagate and modified Booth multipliers, in this paper we propose new ...
