A Note on ``Linear-Communication ACSS with Guaranteed Termination and Lower Amortized Bound''
Abstract
In this note, we demonstrate that the construction of asynchronous complete secret sharing (ACSS) proposed in the recent work by Qin et al., accepted at Eurocrypt 2026, is insecure. In particular, we identify several issues affecting the liveness of their protocol and present attacks that compromise its correctness.
