MIBS: A New Lightweight Block Cipher

2009
In this paper, we propose a new lightweight 64-bit block cipher, which we call MIBS, suitable for resource-constrained devices, such as low-cost RFID tags. We also study its hardware implementation efficiency, as well as its security. The hardware implementation of MIBS requires 1400 gates on 0.18 μm technology, which is less than 2000 gates limit for ...

Implementation and Cryptanalysis of Lightweight Block Ciphers

2020 4th International Conference on Trends in Electronics and Informatics (ICOEI)(48184), 2020
Encryption has become an important need for each and every data transmission. Large amount of delicate data is transferred regularly through different computer networks such as e-banking, email applications and file exchange. Cryptanalysis is study of analyzing the hidden information in the system.

QTL: A new ultra-lightweight block cipher

Microprocessors and Microsystems, 2016
Abstract We propose a new ultra-lightweight block cipher, QTL. The 64 bits block cipher QTL supports 64 and 128 bits keys. To solve the slow diffusion of the traditional Feistel-type structures we have used a new variant of generalized Feistel network structure in design of the QTL.

FPGA implementation of LBlock lightweight block cipher

2016 3rd International Conference on Electrical Engineering and Information Communication Technology (ICEEICT), 2016
The ubiquitous computing era is characterized by wide deployment of resource constraint devices. Secure communication between such devices encounters a big challenge due to their resource limitation. The lightweight cryptographic algorithms are developed to address this challenge.

FeW: A Lightweight Block Cipher

2018
In this paper, we propose a new lightweight block cipher \textit{FeW} which encrypts plaintext in the blocks of 64-bit using 80/128 bits key to produce 64-bit ciphertext. We also propose a new structure namely \emph{Feistel-M structure} by admixture of Feistel and 4-branch  generalised Feistel structures. This new structure significantly contributes to

OLBCA: A New Lightweight Block Cipher Algorithm

2014 3rd International Conference on Advanced Computer Science Applications and Technologies, 2014
Light weight block cipher algorithms are vital for constrained environment. It is easy to propose an algorithm that optimize any two factors like (security and cost), (security and performance) and (cost and performance) but it is difficult to optimize three factors together at the same time.

Lightweight block ciphers for resource-constrained devices

2020 12th International Symposium on Communication Systems, Networks and Digital Signal Processing (CSNDSP), 2020
Lightweight cryptography is a new branch of cryptography focused on providing security to resource-constraint devices such as wireless sensor networks (WSN), Radio-Frequency Identification (RFIDs) and other embedded systems. The factors considered in lightweight cryptography are mainly circuit area, memory requirement, processing time, latency, power ...

LiCi: A new ultra-lightweight block cipher

2017 International Conference on Emerging Trends & Innovation in ICT (ICEI), 2017
In this paper, we have presented a new lightweight, low power block cipher “LiCi”. The cipher LiCi has Feistel based network which operates on 64 bits plain text and with the help of 128 bits key length it generates 64 bits cipher text. This cipher design shows good performance both on hardware as well as on software platforms.

The SIMON and SPECK lightweight block ciphers

Proceedings of the 52nd Annual Design Automation Conference, 2015
The Simon and Speck families of block ciphers were designed specifically to offer security on constrained devices, where simplicity of design is crucial. However, the intended use cases are diverse and demand flexibility in implementation. Simplicity, security, and flexibility are ever-present yet conflicting goals in cryptographic design.

Lightweight block ciphers with applications in IoT

2019
This chapter aims to provide a comprehensive survey of lightweight block ciphers that have been designed for resource-constrained IoT platforms. The implementations of 10 lightweight block ciphers are compared on 8-bit, 16-bit, and 32-bit microcontrollers by using evaluation metrics such as power and energy consumption, latency, security level ...
