Software-hardware facilities for cryptosystems based on polynomial RNS

This paperis dedicated to the development of software-hardware facilities for cryptosystems based on polynomial residue number system. Today, there is a significant increase in the transfer and processing of personal data from different sources, and this huge amount of data is stored in various information systems and environments. There arc many security threats to sensitive data that arc processed and stored on such systems. One of the most reliable ways to solve data protection problems in computer systems and networks is data encryption. With the development of communication networks and embed systems, there is a growing need to create efficient hardware solutions for performing encryption. The most of the known conventional software-hardware cryptosystems arc implemented using positional number system. The main difficulty with performance occurs during work with large data blocks (for instance, with long encryption keys) in cryptographic transformations. As a result of searching for ways to increase the productivity of electronic computers, methods of detecting and correcting errors, and building highly reliable computer systems, in the middle of the 20th century research has begun in the field of non-positional notation systems...
