We present a round addition differential fault analysis (DFA) for some lightweight 80-bit block ciphers. It is shown that only one correct ciphertext and two faulty ciphertexts are required to reconstruct secret keys in 80-bit Piccolo and TWINE, and the reconstructions are easier than 128-bit CLEFIA.
