An ultra-lightweight block cipher with string transformations

Cryptologia, 2023
Security efficiency and hardware efficiency are equally important when designing a block cipher. In this paper, we propose a new block cipher that uses string transformations and requires less memory and fewer computational resources, making it suitable ...

Design of Chaotic Block Cipher Operation Mode for Intelligent Transportation Systems

IEEE International Conference on Consumer Electronics, 2019
Information security is a vital aspect of Intelligent Transportation Systems (ITS) involving public data collection. Road images captured for use as a basis of traffic manipulation in ITS should take all precautions for encrypting the wirelessly ...

Symmetric Encryption Scheme Based on Quasigroup Using Chained Mode of Operation

Journal of Discrete Mathematical Sciences and Cryptography
In this paper, we propose a novel construction for a symmetric encryption scheme, referred as SEBQ which is built on the structure of quasigroup. Utilizing the concepts of chaining like mode of operation, SEBQ is a block cipher with various in-built ...
