The encrypted contest file is the exact material available to any criminals, hackers, or qualified scientists if Whitenoise PC File Security for personal security and Secure File Interchange [SFI] for the secure exchange of digital content over IP based networks are used properly.
The encrypted contest file is encrypted with Whitenoise. Whitenoise utilizes a multiple sub-keys structure that is a minimum of 240,000 bits in strength and which generates random key streams greater than 1060 bytes in length.
The contest file has the Whitenoise key offset embedded in its 77-byte header and the entire file is encrypted.
Whitenoise understands the general rules of cryptanalysis. It is considered that there is always key stream material available. So, the contest file will include a 1 Megabyte chunk of key stream data from the key used to encrypt the contest file. The Whitenoise web site www.wnlabs.com contains patent papers and multiple presentations on how Whitenoise keys are constructed and properly utilized. Feel free to scrutinize these presentations and papers before attempting your break.
Please download the contest rules, the contest challenge file and the key stream chunk from wnlabs.com/WhitenoiseSecurityChallenge.
