Jeong‐Soo Park, YongJe Choi, Dooho Choi, Jaecheol Ha · Information Security and Cryptology · 2012
The fault injection attack has been developed to extract the secret key which is embedded in a crypto module by injecting errors during the encryption process. Especially, an attacker can find master key of AES using injection of just one byte. In this paper, we proposed a countermeasure resistant to the these fault attacks by checking the differences between input and output. Using computer simulation, we also verified that the proposed AES implementation resistant to fault attack shows better fault detection ratio than previous other methods and has small computational overheads.
