Enhanced Dictionary Based Rainbow Table

Abstract : As users become increasingly aware of the need to adopt strong password, it brings challenges to digital forensics investigators due to the password protection of potential evidentiary data. On the other hand, due to human nature and their tendency to select memorable passwords, which compromises security for convenience, users may select strong passwords by considering a permutation of dictionary words. In this paper, we discuss the existing password recovery methods and briefly present our previous work on the design of a time-memory tradeoff pre-computed table (Enhanced Rainbow Table) for efficient random password recovery. We then propose the design of an Enhanced Dictionary Based Rainbow Table to integrate the construction of dictionary based permutated passwords and common passwords within the Enhanced Rainbow Table, to incorporate the two promising password recovery approaches. We then present the analysis of the proposed method.
