Summary: 
In this paper, the round addition differential fault analysis (DFA) using operation skip for Feistel-type block ciphers is presented. This attack method is based on supplying abnormal voltage to cipher-implemented microcontrollers without depackaging and microscopic operations. It is shown that only one correct ciphertext and one or two faulty ciphertexts are required to reconstruct the secret key.
