MIBS: A New Lightweight Block Cipher

Lecture Notes in Computer Science, 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 ...

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.

µ2 : A Lightweight Block Cipher

, 2020
This paper presents a 64-bit lightweight block cipher, µ2 with a key size of 80-bit. µ2 is designed based on well-established design paradigms, achieving comparable performance and security when compared against existing state-of-the-art lightweight block ciphers. µ2 is based on the Type-II generalized Feistel structure with a round function, F that is

A Review on Lightweight Block Ciphers

SSRN Electronic Journal, 2020
Lightweight cryptography has been very important for the last few years. It became one the most important block of a secure embedded systems because it has been a strong requirement for any resource constrained devices, and has several features like, it consumes only less power, less memory, etc.

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.

Shadow: A Lightweight Block Cipher for IoT Nodes

IEEE Internet of Things Journal, 2021
The advancement of the Internet of Things (IoT) has promoted the rapid development of low-power and multifunctional sensors. However, it is seriously significant to ensure the security of data transmission of these nodes. Meanwhile, sensor nodes have the characteristics of converting analog signals into digital signals for operation processing in ...

TWIS – A Lightweight Block Cipher

2009
A new 128-bit block cipher, TWIS is proposed. It uses key size of 128-bits. The design targets to software environment for resource constrained applications. It is inspired from existing block cipher, CLEFIA. Although the proposed design uses less resources as compared to CLEFIA, it compares favorably with CLEFIA in terms of security provided.

Improved algebraic attacks on lightweight block ciphers

Journal of Cryptographic Engineering, 2020
This paper proposes improved algebraic attacks that are effective for lightweight block ciphers. Concretely, we propose a new framework that leverages on algebraic preprocessing as well as modern SAT solvers to perform algebraic cryptanalysis on block ciphers.
