Title:
On Misuse of Nonce-Misuse Resistance: Adapting Differential Fault Attacks on (few) CAESAR Winners
Authors: Mustafa Khairallah, Shivam Bhasin, Anupam Chattopadhyay
Abstract:In this paper, we study DFA attacks on some of the CAESAR competition winners. We study the challenges imposed by the design of these modes, such as masking of the ciphertext. We also show that a very small number of nonce repetition and faults is required, which makes it very practical. We show that OCB and COLM need 1 nonce repetition and 3 faults only to uniquely identify the Key.
