Experimental Studies Of The Modern Symmetric Stream Ciphers

The paper is a continuation of numerous studies of a candidate for encryption national standard of Ukraine, the Strumok new symmetric stream cipher. The result of a study is compare the most famous algorithms of stream cipher, which were presented at various contests, such as eSTREAM, NESSIE and the AES symmetric block cipher in mode of stream about usage CPU time for transformation of one octet data.
