Absract. The main aim of the paper is selection of criteria for evaluation and analysis of lightweight ciphers with different structure and modes of operation to serve in the
subsequent comparative analysis of selected ciphers, finalists in the NIST’s competition for
new lightweight cryptographic algorithm. Methods used: comparative analysis and
summary. Based on the study, two types of criteria were selected - to assess the capabilities of ciphers and to assess their software performence. The first type of metrics has been applied on representatives of two families of lightweight ciphers, finding which have better characteristics.
Keywords: lightweight algorithms; criteria; comparative analysis
