This work presents the main developing results of a new keystream generator, which named “Strumok”, and offered as a candidate for the national symmetric encryption standard of Ukraine. “Strumok” is built on SNOW 2.0-likes schema of the summation generator. Increased secret key length and the initialization vector allow using reliably the stream cipher even taking into account quantum cryptographic analysis methods. Unlike SNOW 2.0, Strumok is designed for use in more powerful 64-bit computing systems. The conducted comparative tests have shown that the “Strumok” on 32-bit computing systems also shows good performance results. There are basic transformation and individual results from the cipher performance research, here is it is shown the generator, which is capable of forming a keystream at speeds exceed of 10 Gbit per sec.
