Several techniques perturbing the computation of a cipher have been devised and successfully employed to leak secret information from erroneous results.
WebSep 1, 2024 · This paper introduces an ARM specific fault injection attack strategy for exploiting embedded systems where externally controlled data is loaded in the program counter (PC) register of the processor, which allows an attacker to control the target's execution flow which eventually will lead to arbitrary code execution on the target. 75 PDF WebJan 1, 2009 · The present paper develops an attack on the AES algorithm, exploiting multiple byte faults in the state matrix. The work shows that inducing a random fault anywhere in one of the four diagonals...
