DEVICE FOR ENCRYPTING DATA ACCORDING TO STANDARDS GOST 28147-89 AND AES Russian patent published in 2013 - IPC G09C1/00 H04L9/06 G06F21/62 

FIELD: information technology.

SUBSTANCE: device for encrypting data includes a GOST 28147-89 conversion circuit, an AES conversion circuit, an AES key conversion unit, a first multiplexer, a second multiplexer, a data storage and a key storage; the output of the data storage is connected to the first input of the GOST 28147-89 conversion circuit and to the first input of the AES conversion circuit; the output of the key storage is connected to the second input of the GOST 28147-89 conversion circuit, the second input of the AES conversion circuit, the input of the AES key conversion unit and the second input of the second multiplexer; outputs of the GOST 28147-89 conversion circuit and the AES conversion circuit are connected to the first and second inputs of the first multiplexer, respectively; the output of the first multiplexer is connected to the input of the data storage; the output of the AES key conversion unit is connected to the first input of the second multiplexer; the output of the second multiplexer is connected to the input of the key storage; encryption algorithm selection signals are transmitted to the control inputs of the first and second multiplexers.

EFFECT: reducing the amount of memory required to encrypt data.
