The LED is a new lightweight cipher, which was published in CHES 2011.This cipher could be applied in the Wireless Sensor Network to provide security.On the basis of the single byte-oriented fault model, we propose a differential fault analysis on the LED cipher.The attack could recover its 64-bit secret key by introducing 4 faulty ciphertexts, and 128-bit secret key by introducing 8 faulty ciphertexts.The results in this study will be beneficial to the analysis of the same type of other iterated lightweight ciphers.
