Loading page content...Lightweight 64-bit Feistel block cipher (ICISC 2011). 80-bit key, 32 rounds. Uses 8 distinct 4-bit S-boxes (S0-S7) in round function, plus S8, S9 in key schedule. Strong provable security against differential/linear cryptanalysis.
Imported traces are validated and replayed locally. They never run a cipher operation automatically.

The original 1994 predecessor to XTEA (also in this registry). Simple ARX Feistel cipher, no S-boxes — but has a documented equivalent-key weakness (4 related keys produce identical ciphertext), which XTEA's extra key mixing was designed specifically to fix.
A compact 64-round Feistel cipher (Wheeler & Needham, 1997) using only addition, XOR, and shifts — no lookup tables.
