METHOD FOR ITERATIVE BLOCK ENCRYPTION OF BINARY DATA

FIELD: electric communications and computer engineering. 

SUBSTANCE: proposed cryptographic method for data encryption includes generation of private key in the form of aggregate of sub-keys, division of data block into m2 sub-blocks B₁,B₂,...,B_m, and conversion of sub-blocks; sub-block B_j, where 1jm, is converted by converting at least one sub-key with aid of controlled operation depending on block B_h, where 1jm and hj, and superposing converted sub-key onto block B_j using two- position operation for the purpose. 

EFFECT: enhanced encryption speed. 3 cl, 2 dwg
