Lightweight block ciphers are used in applications where low power consumption is a requirement along with hardware area constraints regarding their implementation. Design of these ciphers demands an optimal tradeoff between computational efficiency and security. These ciphers being supportive in fast and secure transmission of data from one location to another are prone to several attacks that...

High Entropy Alloys (HEAs) are the most recently developed new class of materials, which are known for their unique structural properties. Lightweight materials are currently in excessive demand for transportation and energy saving applications. In this review, efforts have been made to summarize the work done towards the development of HEAs targeting lightweight applications. Some new synthesi...

This article is focused on lightweight aggregate-concrete modified by municipal sewage sludge and lightweight aggregate-concrete obtained from light aggregates. The article presents laboratory examinations of material physical parameters. Water absorptivity of the examined material was decreased by the admixture of water emulsion of reactive polysiloxanes. Water transport properties were determ...

RFID technology is one of the major applications of lightweight cryptography where security and cost both are equally essential or we may say that cost friendly cryptographic tools have given more weightage. In this paper, we propose a lightweight hash, Neeva-hash satisfying the very basic idea of lightweight cryptography. Neeva-hash is based on sponge mode of iteration with software friendly p...

This paper presents the design of a lightweight, yet software friendly, block cipher. Most of the lightweight block ciphers are nibbleoriented as the implementation of a 4-bit S-box is much more compact than an 8-bit S-box. This paper uses a novel implementation of multiplicative inverse for 8-bit S-boxes using LFSR requiring only 138 gateequivalent. With this powerful scheme, we design a light...
