Observations on the DLCT and Absolute Indicators
boolean functions DLCT ACT
font style='font-size:12px;'>
2019/7/23
Recently Bar-On et al. proposed the DLCT for a tighter analysis of probabilities for differential-linear distinguishers. We extend the analysis of the DLCT, and gain new insights about this notion.
