Block cipher DEFAULT has been proposed as a differential fault analysis immune cipher at Asiacrypt 2021.
In this paper, we show that one can find the key of the initial version of DEFAULT with complexity $2^{16}$ by injecting 112 faults. However, our idea does not work in the modified
version of the cipher.
