This paper introduces Multi-Stage Fault Attacks, which allow Differential Fault Analysis of block ciphers having independent subkeys. Besides the specification of an algorithm implementing the technique, we show concrete applications to LED-128 and PRINCE and demonstrate that in both cases approximately 3 to 4 fault-injections are enough to reconstruct the full 128-bit key.
