Development of a New Lightweight Encryption Algorithm

Due to the growing need use devices with low hardware resources in everyday life, likelihood of their susceptibility various cyber-attacks increases. In this regard, one methods ensure security information circulating these is encryption. For small resources, most applicable low-resource (lightweight) cryptography. This article introduces a new lightweight encryption algorithm, ISL-LWS (Information Security Laboratory – system), designed protect data on resource-constrained devices. The algorithm implemented C++ programming language. paper presents statistical properties ciphertexts obtained using developed algorithm. experimental testing for security, sets tests by NIST and D. Knuth were used. Separately, was tested avalanche effect properties. results compared Present Speck modern algorithms. study comparative analysis speed key generation three algorithms carried out Arduino Uno R3 board.
