- Abstract
Based on the ciphertext-only assumption,the existing distinguishers such as squared Euclidean imbalance, Hamming weight, maximum likelihood and goodness of fit, and new distinguishers such as ratio distance, ratio distance-Hamming weight and ratio distance-maximum likelihood were used to recover the original key of the lightweight cipher LEA using the distribution properties of intermediate state values after fault injection. The results show that LEA cipher cannot resist ciphertext-only fault analysis, and the new distinguishers require at least 396 faults to decipher LEA cipher with a success rate of 99% and above, which not only effectively reduces the number of faults, but also improves the attack efficiency. The research results provide a reference for the secure design and implementation of lightweight cryptosystems with the same structure in the IoT(Internet of Things) environment.
