Ciphertext-only fault analysis of the TWINE lightweight cryptogram algorithm.

The security analysis of TWINE against the ciphertext-only fault analysis was proposed. The secret key of TWINE could be recovered with a success probability at least 99% using a series of distinguishes of SEL MLE, HW, GF, GF-SEI, GF-MLE, Parzen-HW, MLE-HE, HW-HE and HW-MLE-HE. Among them, the novel proposed distinguishes of MLE-HE, HW-HE and HW-MLE-HE can effectively reduce the faults and improve the attack efficiency in simulating experiments. It provides a significant reference for analyzing the security of lightweight ciphers in the Internet of Things. [ABSTRACT FROM AUTHOR]
