Historically leakage attacks were categorised in two simple classes: using multiple observations of a single leaking target variable (DPA style) vs. using a single observation of many leaking target variables (SPA style). During the last year we have seen several attempts to bridge the gap, i.e. methodologies that exploit the leakage of several leaking variables using multiple observations. I want to explain these different methods, their computational requirements, and examine in which contexts they are applicable. An important factor in this context that I want to address briefly is that of efficient key enumeration (based on the score vectors that result from leakage attacks).
