Executive Summary

The goal of cryptanalysis is to assess the security of cryptographic primitives. Finding attacks or properties not present in ideal instances typically contributes to the cryptanalysis of a given primitive. Building upon previous results, attacks can be improved over time, possibly up to a point where the security of the primitive is severely questioned. In contrast, cryptanalysis can also benefit from positive results that exclude classes of attacks, thereby allowing research to focus on potentially weaker aspects of the primitive.
