Algebraic attacks on stream ciphers exploit annihilators of low degree. From another point of view, we concentrate on annihilators in fewer variables in this paper. This work consists of two parts. Firstly, the concep...

Low differential uniformity functions provide good resistance to differential attacks. The AES (Advanced encryption standard) uses a differentially 4 uniform function (the inverse function) as its S-box. We give a...
