Weaknesses in the Key Scheduling Algorithm of RC4
TL;DR: It is shown that RC4 is completely insecure in a common mode of operation which is used in the widely deployed Wired Equivalent Privacy protocol (WEP, which is part of the 802.11 standard), in which a fixed secret key is concatenated with known IV modifiers in order to encrypt different messages.

Statistical Analysis of the Alleged RC4 Keystream Generator
Scott R. Fluhrer,David McGrew +1 more
TL;DR: A method for distinguishing 8-bit RC4 from randomness is demonstrated and it is observed that an attacker can, on occasion, determine portions of the internal state with nontrivial probability.

Method and apparatus to minimize database exchange in OSPF by using a SHA-1 digest value
TL;DR: In this paper, a hash function on the values contained in a link state database to derive a SHA-1 digest value is used to determine whether a database located on a first router is synchronized with another database located at a second router.
Book ChapterDOI
Analysis of the E0 Encryption System
Scott R. Fluhrer,Stefan Lucks +1 more
TL;DR: A method of deriving the cipher key from a set of known keystream bits is given, which provides an upper bound on the amount of security that would be made available by enlarging the encryption key, as discussed in the Bluetooth specification.

The Extended Codebook (XCB) Mode of Operation.
David McGrew,Scott R. Fluhrer +1 more
TL;DR: XCB as discussed by the authors is a block cipher mode of operation that implements a "tweakable" (super) pseudorandom permutation with an arbitrary block length, which can be used to provide the best possible security in systems that cannot allow data expansion.
