On Boolean Functions with Generalized Cryptographic Properties
An Braeken, Ventzislav Nikov, Svetla Nikova, Bart Preneel
Abstract: By considering a new metric, we generalize cryptographic
properties of Boolean functions such as resiliency and propagation
characteristics. These new definitions result in a better understanding
of the properties of Boolean functions and provide a better insight in
the space defined by this metric. This approach leads to the
construction of ``hand-made'' Boolean functions, i.e., functions for
which the security with respect to some specific monotone sets of inputs
is considered, instead of the security with respect to all possible
monotone sets with the same cardinality, as in the usual definitions.
This approach has the advantage that some trade-offs between important
properties of Boolean functions can be relaxed.
