Differential fault attack on DEFAULT

Chandan Dey, Sumit Kumar Pandey, Tapabrata Roy, and Santanu Sarkar

Abstract

Block cipher DEFAULT has been proposed as a differential fault analysis immune cipher at Asiacrypt 2021. In this paper, we consider the initial version of DEFAULT with no permutation involved in the last round and show that one can find the key in this version with complexity $2^{16}$ by injecting 112 faults. However, our idea does not work in the modified version of the cipher.
