Experimental evaluation of differential fault attack on lightweight block cipher PIPO

The recent development of Internet Things (IoT) devices has increased related security issues. Because the rapid increase in use these devices, possibility accessing and hijacking cryptographic is increasing. Consequently, active research on technologies capable providing a safe environment even resource-constrained environments been undertaken. As result their physical accessibility, are becoming more vulnerable to Side-channel analysis (SCA) To address issues, PIPO, lightweight block cipher, was recently proposed ICISC 2020. PIPO characteristic robust strength while having less overhead when using SCA countermeasures. A Differential fault attack (DFA) type that induces operations utilises difference information occurs. attacks have not yet studied. For first time, this study single-bit flip-based DFA PIPO. Through 64 ciphertexts, 98.8% probability recovering correct secret key 64/128. We evaluated only through simulation but also electromagnetic injection (FI). Hereinafter, we were able confirm our being applied real world devices. Therefore, without FI countermeasure provides no against differential attacks. When cipher IoT designers must appropriate countermeasures
