NEW ALGORITHM OF BLOCK ENCRYPTION OF DATA WITH THE SYMMETRIC KEY
Д. Е. Акбаров, Shukhratjon Umarov · Bulletin of Kyiv Polytechnic Institute Series Instrument Making · 2016
In this article, continuing idea of development of the symmetric block data encryption algorithms which aren't based on Feystel's network the new symmetric block algorithm is offered.In the offered algorithm are used a combination of conversions: bit-by-bit addition on mod2, matrix transformation on mod256, the S-unit and the table of compression, realizes encoding 128 (in modification 128+32l) bit data units by means of 128 (in modification 128+32l) a bit key of k, where l=1,2,…, d, d<.
