Involutory transformation
Webinvolutory transformations. It is not known if an analogous theorem holds for non-linear transformations and suitably restricted groups. A converse proposition is to the effect that … Web9 jan. 2013 · In the design of VGF2, the original idea to achieve better diffusion is to use an involutory transformation with good branch number to replace the switch transformation. In , security levels of the structure against many cryptanalysis such as differential, linear, impossible differential, and integral cryptanalysis are also estimated.

There exists a linear transformation f which sends e 1 to e 2, and sends e 2 to e 1, and which is the identity on all other basis vectors. It can be checked that f(f(x)) = x for all x in V. That is, f is an involution of V. For a specific basis, any linear operator can be represented by a matrix T.
