Research of cross-platform stream symmetric ciphers implementation

In this paper, the modern symmetric stream ciphers Enocoro, Decim, Grain, HC, MUGI, Mickey, Rabbit, RC-4, Salsa20, SNOW2.0, Sosemanuk, Strumok, Trivium, and a block cipher AES, which can be used in streaming encryption modes, are being researched. The main results of testing the rate of formation of a key stream with cross-platform implementation of encryption algorithms in the Java programming language on operating systems Windows 10 (x64), Debian (Kali) and Android (x64) are presented. Testing was conducted on a portable personal computer (Intel Pentium 3550m 2.3ΓΓII, RAM 4Γ6 (1600MII)) and on a mobile device, in particular, on a smartphone (Samsung galaxy S7).
