Performance Evaluation of Newly Proposed Lightweight Cipher, BRIGHT

Abstract

Lightweight security algorithms are tailored for resource-constrained environment. To improve the efficiency of an algorithm, usually, a tradeoff is involved in lightweight cryptography in terms of its memory requirements and speed. By adopting several performance enhancement techniques, a security framework for IoT enabled applications is presented in this paper. Proposed BRIGHT family of ciphers is comparably better than existing lightweight ciphers and support a range of block and key sizes for constraint environment. It enables users to match their security needs with application requirements by supporting a range of cryptographic solutions. The BRIGHT family of ciphers is a software-oriented design. The performance of BRIGHT family of lightweight ciphers is evaluated on different parameters. All versions of BRIGHT family ciphers fulfill Strict Avalanche Criteria, key sensitivity test, and randomness test. BRIGHT family ciphers show better performance in terms of memory requirements, cost and speed as compared to existing lightweight ciphers.

IoT Based Human Activity Recognition System Using Smart Sensors

“…Numerous researchers in the area of IoT security has given different lightweight security algorithms. Moving in the same direction, we have also proposed three different lightweight security algorithms, BRIGHT [28], [29], [30], and UBRIGHT [31]. A total of 9 different security algorithms are proposed in these three security algorithms.…”

A Review on Performance Evaluation Criteria and Tools for Lightweight Block Ciphers

“…Stream ciphers are symmetric key ciphers and are mainly used in those applications where plaintext size is unknown. Although, stream ciphers have a simple and speedy implementation in hardware but due to lengthy initialization phase and also due to some of the communication protocols that do not utilize stream ciphers, these are less preferred over block ciphers and as a result does not receive much attention [6,49]. TRIVIUM: Trivium is a simple, speedy, smallest and most efficient bit-oriented stream cipher which provides good security margin against attacks and requires low power hardware implementation [50,51].…”

“…These can be implemented either through software implementation or through hardware implementations. Software oriented cipher designs provide more flexibility at lower costs on manufacturing and maintenance as compared to hardware implementations [6]. This is because of its ability to provide efficient end-to-end communications [7].…”

Bright - Proposed Family of Lightweight Block Ciphers for IoT-Enabled Smart Environment

“…It is verified that all versions of BRIGHT family fulfill SAC criteria and key sensitive test. Besides, performance of BRIGHT is evaluated on different parameters and compared with various benchmarked lightweight block ciphers on different platforms (64-bit and 32-bit) which are culminated in the publications [15,16].
