Some Results on the Degenerate Criterion of Cryptographic Functions over Finite Fields
Jihong Teng, Xiaoying Huang, Weiming Zhang · 2010
The paper reveals the relationship between degenerate criterion and Chrestenson spectra of cryptographic functions over finite field. Two examples are proposed to show how we can decide whether a cryptographic function is degenerate through the support of its Chrestenson spectra, which can make us construct cryptographic function to resist substitution attacks by a new function with fewer variables.
