Title:
The Perils of Repeating Patterns: Observation of Some Weak Keys in RC4
Authors: Joachim Strömbergson, Simon Josefsson
Abstract:We describe some observed trivially weak keys for the stream cipher RC4. Keys with repeating patterns are found to be key length invariant. The cause of the problem is the simplistic key dependent state permutation in the RC4 initialization.
