Foreword
Bent functions are fascinating mathematical objects. They were discovered by cryptographers who were searching for functions that are difficult to approximate by linear or affine functions. Bent functions are defined as functions that are at maximum distance to such weak functions. Bent functions were discovered independently by cryptographers in the US National Security Agency and in the Soviet Union; both nations decided to classify the results as confidential.
After one decade, Rothaus was allowed to publish his groundbreaking paper; it appeared in a journal on combinatorics in 1976. Around the same time (in 1972), Dillon published his seminal PhD thesis on elementary Hadamard difference sets. The first application area of bent ...
