Investigation of the different implementations for the new cipher Qamal

Currently, the Republic of Kazakhstan is creating a new standard for symmetric data encryption. Qamal encryption algorithm developed by the Institute of Information and Computer Technologies (Almaty, Republic of Kazakhstan), which is one of the candidates to be approved as a standard, is the subject of our study. We analyze in detail the basic cipher transforming work principles, approaches to its quick implementation and the results of the implementation experiments in several programming languages. The encryption algorithm under study uses the round subkeys generating procedure, which seems to be several times more complicated than the single block processing procedure. The software implementation approaches suggested can significantly reduce computation time by using logic operations instead of accessing data arrays. Our article is the first step to a comprehensive research of Qamal properties; its resistance to different cryptanalysis types is yet to be analyzed.
