  • implementing rainbow tables in high end fpgas for super fast Password cracking
    Field-Programmable Logic and Applications, 2010
    Co-Authors: Ioannis Papaefstathiou, Charalampos Manifavas
    Abstract:

    One of the most efficient methods for cracking Passwords, which are hashed based on different cryptographic algorithms, is the one based on “Rainbow Tables”. Those lookup tables offer an almost optimal time-memory tradeoff in the process of recovering the Plaintext Password from a Password hash, generated by a cryptographic hash function. In this paper, the first known such generic system is demonstrated. It is implemented in a state-of-the-art reconfigurable device that cracks Passwords, which are encrypted with a number of different cryptographic algorithms. The proposed FPGA-based system is up to 1000 times faster than the corresponding software approach. This is achieved by using a highly parallel architecture employing a fine-grained pipeline.

    Abstract:

    One of the most efficient methods for cracking Passwords is the one based on ldquorainbow tablesrdquo; those lookup tables are offering an almost optimal time-memory tradeoff in the process of recovering the Plaintext Password from a Password hash generated by a cryptographic hash function. In this paper, we demonstrate the first known system, implemented in a state-of-the-art reconfigurable device that cracks Passwords up to 1000 times faster than the software approach.

  • A study on one way hashing function and its application forFTMSK webmail / Noor Hasimah Ibrahim Teo
    2005
    Co-Authors: Ibrahim Teo, Noor Hasimah
    Abstract:

    Password is a normal way for securing data from intruders. The widespread use of Password is in email account. The advances of technology have reduced the function of Password in security, where there are many chances of Password to be sniffed or hack by intruders. FTMSK webmail is using Password as an authentication method. The problem was, their lecturer is not allowed to send examination question through email. This means that they do not trust the security of webmail. There are several techniques use to transform Plaintext Password to other form of Password. One of it is call one-way hashing function. One-way hashing function consists of several algorithms. However MD5 is the most common hashing function currently in use. The research are aim to detemriine security of using one way hashing function at client side for FTMSK webmail login system and design framework for one way hashing function. A prototype is developed using MD5 algorithm and based on prototype approach, since it study on existing system. Tests are run for both FTMSK webmail and prototypes to determine whether the plain text Password can be retrieved. Furthermore framework for one way hashing function is designed. Password need to be store in database on server in the form of hashing value. Secure Password during transmission can be obtained by running protection on the client side of client server architecture.
