Abstract

Highly nonlinear balanced Boolean functions both satisfying the propagation criterion and having almost uniform correlation values with all linear functions are very important in the design of hash functions, stream and block ciphers. In particular, the output uncorrelated properties between two Boolean functions are required to design permutations. We present, so called, semi-bent functions which satisfy all of these properties.KeywordsBoolean FunctionHash FunctionPropagation CriterionBlock CipherStream CipherThese keywords were added by machine and not by the authors. This process is experimental and the keywords may be updated as the learning algorithm improves.
