Algebraic fault attack on LED light-weight block cipher
轻型分组密码LED代数故障攻击方法

This paper applied a new algebraic fault attack on LED, which was a light-weight block cipher proposed in CHES 2011. Firstly, the algebraic representations of LED were described. Secondly, the fault differences of ciphertext based on single bit fault model were represented as algebraic equstions. Finally, it applied the CryptoMiniSAT solver to solve the equstions. Experiments demonstrate that algebraic fault attack is better than traditional differential fault analysis for LED, one fault injection at the 30th round is enough to recover the 64 bit master key of LED in 122s.
