Analysis of the Perfect Table Fuzzy Rainbow Tradeoff

Abstract EN

Cryptanalytic time memory tradeoff algorithms are tools for inverting one-way functions, and they are used in practice to recover passwords that restrict access to digital documents.

This work provides an accurate complexity analysis of the perfect table fuzzy rainbow tradeoff algorithm.

Based on the analysis results, we show that the lesser known fuzzy rainbow tradeoff performs better than the original rainbow tradeoff, which is widely believed to be the best tradeoff algorithm.

The fuzzy rainbow tradeoff can attain higher online efficiency than the rainbow tradeoff and do so at a lower precomputation cost.
