Improving Performance Counter Estimates

One area in particular that the author feels could benefit from further research has to do with refining the technique used to calculate the performance counter. As was illustrated in figure 5.7, a more thorough analysis of the apparent association between time and the lower 17 bits of the performance counter is necessary. This analysis would directly affect the ability to recover more cookie state information, since the entropy of the lower 17 bits of the performance counter is one of the only things standing in the way of obtaining the entire cookie.
