Visualizing size-security tradeoffs for lattice-based encryption

Daniel J. Bernstein

Abstract: There are many proposed lattice-based encryption systems. How do these systems compare in the security that they provide against known attacks, under various limits on communication volume? There are several reasons to be skeptical of graphs that claim to answer this question. Part of the problem is with the underlying data points, and part of the problem is with how the data points are converted into graphs.
