Rainbow Table TMTO Attack Optimization Considering Online Sequential Search Time

In this paper, we propose an optimizedparameter selection procedure for rainbow table TimeMemory Trade-Off (TMTO) attack with sequential onlinesearch. Unlike previous works that mainly deal withminimizing required memory in the rainbow table TMTOattack, we simultaneously focus on the required memory andonline search time. Our parameter selection technique isoptimized regarding the minimization of the requiredmemory subject to a certain success probability and amaximum online search time. Obtained results are twocompact mathematical expressions for determining rainbowtable TMTO attack parameters, number and length ofchains. The application of our optimized parameter selectionprocedure is also shown in a sample example.
