Abstract

The issues оn hardware implementation of a cryptodevice based on the Playfair algorithm have been studied. The mathematical substantiation of the algorithm is presented, a permanent memory device for storing the original and modified tables and a block diagram of the algorithm for loading text symbols and a cryptokey are developed. A block diagram of a cryptodevice based on the Playfair algorithm is designed and its performance and hardware costs are estimated from the point of view of FPGA resources.
