A Lightweight block cipher based on quasigroups
The extensive deployment of tiny computing devices,such as sensors,tablets and smart phones,present a requirement for encryption systems fit for low-resource equipments.Despite implementation advances,Advanced Encryption Standard(AES)is not suitable for extremely constrained environments such as sensor networks and smart phones.In this paper,we give a new lightweight block cipher based on quasigroups.A quasigroup can be viewed as a series of S-boxes.All the S-boxes of the quasigroup used in this new cipher are optimal in linearity and differential uniformity,and all the components of these S-boxes have the highest algebraic degree.We compare the performance of this new cipher with AES by using the NIST-STS,the randomness of the new cipher is better than that of AES.
