Since a linear transformation has the form, (1) applying the transformation a second time gives (2) … WebHouseholder matrix. by Marco Taboga, PhD. The Householder matrix (or elementary reflector) is a unitary matrix that is often used to transform another matrix into a simpler one. In particular, Householder matrices are often used to annihilate the entries below the main diagonal of a matrix.

WebA linear diffusion layer is a linear transformation over (Fm 2) n, where m is the bit length of an S-box and n is the number of S-boxes that the linear diffu-sion layer acts on. Note that every linear transformation can be represented by a c International Association for Cryptologic Research 2016 T. Peyrin (Ed.): FSE 2016, LNCS 9783, pp. 121 ... 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. Meer weergeven In mathematics, an involution, involutory function, or self-inverse function is a function f that is its own inverse, f(f(x)) = x for all x in the domain of f. Equivalently, applying f … Meer weergeven Any involution is a bijection. The identity map is a trivial example of an involution.
