In this paper, we extend the applicability of differential meet-
in-the-middle attacks, proposed at Crypto 2023, to truncated differen-
tials, and in addition, we introduce three new ideas to improve this type
of attack: we show how to add longer structures than the original pa-
per, we show how to improve the key recovery steps by introducing some
probability in them, and we combine …
