Abstract
Since an attacker can occur an error in cryptographic device during encryption process and extract secret key, the fault injection attack has become a serious threat in chip security. In this paper, we show that an attacker can retrieve the 128-bits secret key using fault injection attack on the for statement of final round key addition in AES implementation. To verify possibility of our proposal, we implement the AES system on ATmega128 microcontroller and try to inject a fault using laser beam. As a result, we can extract 128-bits secret key through just one success of fault injection.
