WebThis equivalence relation induces a partition on the set of n-bit functions, where a function belongs to the a ne class containing all its a ne equivalent functions. We denote the set of self-equivalences of F by SE(F), the set of left self-equivalences by LSE(F), and the set of right self-equivalences by RSE(F), i.e., SE(F) = f(A;B) 2AGL n AGL
Webjective APN function family by introducing a strong group theoretic method for those functions. Roughly half of the known APN families of functions on even dimensions are biprojective. By our method, we settle the equivalence problem for all known biprojective APN functions. Fur-thermore, we give a new family of biprojective APN functions. WebStream Cipher Equivalence We consider (nonlinear) equivalence of LFSR-based stream ciphers using basic properties of Galois elds. We thus construct isomorphism classes of stream ciphers. The topic has been studied before in the context of block ciphers (e.g. [BB02], [MR02]). In our case, we show however that several important cryptographic

We give a short proof about the dimension of one of these codes. We slightly extend the known concepts of equivalence to the more general case of functions F 2 n to F 2 n. Moreover, we show that CCZ equivalence is the same as extended affine equivalence if f is a vectorial bent function.
