| Abstract(in English) | Rainbow table is a method to crack the password in high speed from hash values. Collision of password candidates occurs, since the table is made by reduction function. To solve this problem, this paper proposes improvement of reduction function, which is used in RainbowCrack, a representative password cracking software which implements rainbow table. This reduction function can be generated collision free tables by same way as DP table. As a result, probability of success was improved 0.138%, memory size was decreased 30.7%, and cracking time was improved 3.9 times compared with collision free tables made from DP table. |
