Query: Proof of a Conjecture about Rotation Symmetric Functions   Rotation symmetric Boolean functions have important applications in the
design of cryptographic algorithms. In this paper, the Conjecture about
rotation symmetric Boolean functions (RSBFs) of degree 3 proposed by Cusik and
St\u{a}nic\u{a} is proved. As a result, the nonlinearity of such kind of
functions is determined.
