On the Feistel Counterpart of the Boomerang Connectivity Table
IACR Transactions on Symmetric Cryptology, 2020 At Eurocrypt 2018, Cid et al. introduced the Boomerang Connectivity Table (BCT), a tool to compute the probability of the middle round of a boomerang distinguisher from the description of the cipher’s Sbox(es). Their new table and the following works led

Titanium S-Boxes: A New Family of 4-bit Optimal S-Boxes for Feistel-Based Lightweight Block Ciphers
IEEE AccessSubstitution boxes (S-boxes) are the main nonlinear components in lightweight block ciphers (LBCs), including Feistel-based designs. Whereas existing S-boxes achieve optimal resistance to differential attacks (DAs), most remain vulnerable to boomerang ...
