Abstract

Modern tasks of information protection permanently demand to increase the performance of the computer means for the symmetric block cipher (SBC) algorithms execution, especially in the multichannel processing of the intensive data streams in the real time scale, thus causing the usage of the application-specific multichannel block cipher processors. In this work the development methodology of the multichannel SBC processors is proposed because of very tedious and complex development cycle, the necessity of the high quality design assuring and design errors elimination. The structure of the application-specific multichannel SBC processor based on dedicated to the channels processing units is the result of the development process by the proposed methodology. Formalization of every design methodology step establishes the preconditions for the creation of the multichannel SBC processors automated development means.
