If you like neat pictures of random bits take a look at page 6 of Playing Hide and Seek with Stored Keys by Shamir et al[1] In this paper we consider the problem of efficiently locating cryptographic keys hidden in gigabytes of data, such as the complete file system of a typical PC. We describe efficient algebraic attacks which can locate secret RSA keys in long bit strings, and more general statistical attacks which can find arbitrary cryptographic keys embedded in large programs. These techniques can be used to apply lunchtime attacks on signature keys used by financial institutes, or to defeat authenticode type mechanisms in software packages. Keywords: Cryptanalysis, lunchtime attacks, RSA, authenticode, key hiding. [1 http://www.cs.jhu.edu/~astubble/600.412/s-c-papers/keys2.pdf http://www.cs.jhu.edu/~astubble/600.412/s-c-papers/keys2.pdf
