摘要
An efficient algorithm to cryptanalyse tree-structured substitution-permutation networks, introduced by Kam and Davida, is presented. The cryptanalysis uses a chosen plain-text approach to construct an equivalent network, working independtly of the network keying. Assuming S-boxes of fixed size, the presented algorithm is shown to be linear in the network block size.
