Algebraic Differential Fault Attacks on LED using a Single Fault Injection

This paper proposes a new fault attack technique on the LED block cipher using a single fault injection by combining Algebraic Side-Channel Attack (ASCA) and Differential Fault Attack (DFA). The authors name it as Algebraic Differential Fault Attack (ADFA). A boolean equation set is constructed for LED using algebraic techniques. Then, the fault differences of the S-Box inputs in the last round of LED are deduced by DFA and represented using algebraic equations by the Multiple Deductions-based ASCA (MDASCA) technique proposed in COSADE 2012. Finally, the key is recovered by solving the equation set with the CryptoMiniSat solver.
