Query: Optimal Equivocation in Secrecy Systems a Special Case of
  Distortion-based Characterization   Recent work characterizing the optimal performance of secrecy systems has
made use of a distortion-like metric for partial secrecy as a replacement for
the more traditional metric of equivocation. In this work we use the log-loss
function to show that the optimal performance limits characterized by
equivocation are, in fact, special cases of distortion-based counterparts. This
observation illuminates why equivocation doesn't tell the whole story of
secrecy. It also justifies the causal-disclosure framework for secrecy (past
source symbols and actions revealed to the eavesdropper).
