A Distributed Cryptanalysis Framework Based on Mobile Phones.

With the development of Internet, there have been many malicious attacks against information system vulnerabilities. Password brute cracking is a kind of classic scene on the condition of powerful processing capability nowadays. In the face of huge key space, a distributed operation mode is required for brute force password attack. We designed a mobile phone-based distributed password analysis system, that is, server serves as DES key fragmentation and encryption, as well as MD5 hashing; mobile terminals perform DES violence analysis and MD5 dictionary attack. At the end, the conclusion and prospect for this architecture are proposed.
