Resumo

This paper describes a symmetrical block cipher tailored to be used on Internet of Things (IoT) environment. It was engineered to be lightweight, consuming less computational resources than other ciphers, like AES, and to work with different block and key sizes. Other important characteristic is to integrate the authentication on its basic algorithm. This approach is helps to reduce the resource needs. The algorithm capacity to resist against linear and different cryptanalysis attacks and to generate was verified. The algorithm was also compared to 23 other ciphers implementations using the metrics generated by the FELICS (DINU et al., 2015) framework. The cipher randomness was also analyzed, using statistical tests.
