INVOLUTIVE PERMUTATION GENERATOR MATRIX Russian patent published in 2012 - IPC G06F7/76 

FIELD: information technology.

SUBSTANCE: device has n-2^k data inputs, n data outputs, control code binary inputs, consisting of switches on n/2 lines - rows and k levels - columns and are controlled and uncontrolled, wherein one of the switches on each of the levels from 1 to k-1 can be uncontrolled; the uncontrolled switches have a first pair of data inputs X11, X21, a second pair of data inputs X12, X22, a first pair of data outputs Y11, Y21, a second pair of data outputs Y12, Y22, and controlled switches have an additional control code binary input and are configured to control connection of inputs with outputs.

EFFECT: high-speed involutive permutation of input data elements.
