Lightweight block cipher TWINE, as a security protection for RFID, smart devices, etc. in artificial intelligence environments, its own security is very important. Analyzed the fault propagation law of lightweight block cipher TWINE and used differential fault analysis method to analyze TWINE. This method is based on the principle of half byte and half random fault attack, and deeply analyzes the degree of differential fault attack on TWINE through multiple rounds of fault propagation. The experimental results show that injecting a total of 4 faults in the 32nd round can fully recover the 80bit seed key, which is the best attack result so far against the differential fault attack of the TWINE algorithm.
