Obtaining of Boolean transformations of special classes for building efficient algorithms of information security

Markovsky A.P., Zyuzya A.A., Sherstyuk V.D.

This paper presents investigation of nonlinear Boolean transformations inverse for which are ambiguous and its application in cryptographical algorithms. A new method for designing such class of Boolean transformations is suggested. The method deals with the procedure form representation of Boolean transformations. It allowed to buil Boolean transformatiom from hundreds Boolean variables. Boolean transformation on such class can be use for accelerate of user identification based on “zero-knoledge” conseption. The relationship between transformation building time and procedure form parameters is established.
