Rotation Symmetric Boolean Functions – Count and Cryptographic Properties
"... Rotation symmetric (RotS) Boolean functions have been used as components of dif-ferent cryptosystems. This class of Boolean functions are invariant under circular translation of indices. Using Burnside’s lemma it can be seen that the number of n-variable rotation symmetric Boolean functions is 2gn, ..."

We study RotS bent functions up to 10 variables and observe (experimentally) that there is no homogeneous rotation symmetric bent function having

"... In 1999, Pieprzyk and Qu presented rotation symmetric (RotS) functions as components in the rounds of hashing algorithm. Later, in 2002, Cusick and Stănică presented further advancement in this area. This class of Boolean functions are invariant under circular translation of indices. In this paper, ..."

, and 15104, RotS bent functions on 4, 6, and 8 variables respectively. Experimental results up to 10 variables show that there is no homogeneous rotation symmetric bent function with degree> 2. Further, we studied the RotS functions on 5, 6, 7 variables for correlation immunity and propagation
Results on Rotation Symmetric Bent and Correlation Immune Boolean Functions
- Fast Software Encryption Workshop (FSE 2004
, 2004
"... Abstract. Recent research shows that the class of Rotation Symmetric Boolean Functions (RSBFs), i.e., the class of Boolean functions that are invariant under circular translation of indices, is potentially rich in functions of cryptographic significance. Here we present new results regarding the Rot ..."

the Rotation Symmetric (rots) correlation immune (CI) and bent functions. We present important data structures for efficient search strategy of rots bent and CI functions. Further, we prove the nonexistence of homogeneous rots bent functions of degree ≥ 3 on a single cycle.
On the Systematic Constructions of Rotation Symmetric Bent Functions with Any Possible Algebraic Degrees
"... In the literature, few constructions of n-variable rotation symmetric bent functions have been pre-sented, which either have restriction on n or have algebraic degree no more than 4. In this paper, for any even integer n = 2m ≥ 2, a first systemic construction of n-variable rotation symmetric bent f ..."

"... This paper discusses homogeneous bent functions. The space of homogeneous func-tions of degree three in six boolean variables was exhaustively searched and thirty bent functions were found. These are found to occur in a single orbit under the action of relabeling of the variables. The homogeneous be ..."

"... It is well known that the degree of a 2m-variable bent function is at most m. However, the case in homogeneous bent functions is not clear. In this paper, it is proved that there is no homogeneous bent functions of degree m in 2m variables when m > 3; there is no homogenous bent function of d ..."

Both the bent and balanced functions discovered have nice algebraic and combinatorial structures. We note that some structures can be extended to a
