This IP core implements the Kuznyechik cipher of the Russian Federation GOST 3412-2015 standard (also available in English as RFC 7801) which replaces the previous 'Magma' algorithm of the GOST 28147-89 standard. The Kuznyechik cipher is structurally similar to AES and has a similar interface.
GOST is of interest for products which must inter-operate with Russian equipment and as a second algorithm to be used in conjunction with AES in applications where it is desired that encrypted data will remain secure even if an attack on AES is discovered or in applications where it is desired to be able to swap-out AES for another algorithm to protect new data should an attack on AES be discovered. For most applications Algotronix recommends the use of AES on both security and performance grounds.
Algotronix can also provide a design service to extend or tailor the core to meet the specific requirements of your application.
