      The article is devoted to improving the performance of cryptographic transformations performed encoders stream ciphers made on the basis of the inner product generator. Such generators are a variety of clock-controlled shift register that can improve the statistical properties of the resulting sequence. The disadvantage is that to get a one character of sequence to submit several clock. The scheme of the inner product generator, based on the algorithm reimplementing feedback shift register recurrence, which allows for one step to produce a single character of sequence, is constructed and described in this article.
