A note on an infeasible linearization of some block ciphers
Riccardo Aragona, Anna Rimoldi, Massimiliano Sala
A block cipher can be easily broken if its encryption functions can be seen as linear maps on a small vector space. Even more so, if its round functions can be seen as linear maps…

The group generated by the round functions of a GOST-like cipher
R. Aragona, A. Caranti, M. Sala
We define a cipher that is an extension of GOST, and study the permutation group generated by its round functions. We show that, under minimal assumptions on the components of the…
