The proposed method of cryptographic transformation of information consists in presenting the information sequence as 128-bit data blocks and performing the iterative processing of the data blocks by the corresponding units using simple operations of cryptographic transformation, such as an operation for substituting bytes according to the fixed byte replacement table, an operation for repeatedly shifting data rows by a specified number of bytes, an operation for mixing data columns, and an operation for adding a coding key. In performing the operation of adding a coding key, a variable function is used that is generated according to an iterative procedure, using the fourth-other matrix that is specified depending on the coding key.
