摘要：
The CAESAR competition is launched in 2013 which aims to find some authenticated encryption with good security and performance. Among these submissions, LAC is designed in a unique way with leaked-state structure. In this paper, based on birthday paradox, we find a forgery attack on LAC in nonce-misused case with time complexity 228. Moreover, we generalize the attack on normal version of leaked-state authenticated encryption and conclude some suggestions on how to use such structure.
