Bounded CCA2-Secure Encryption
Abstract. Whereas encryption schemes withstanding passive chosenplaintext attacks (CPA) can be constructed based on a variety of computational assumptions, only a few assumptions a...

A Practical Attack on the Fixed RC4 in the WEP Mode
In this paper we revisit a known but ignored weakness of the RC4 keystream generator, where secret state info leaks to the generated keystream, and show that this leakage, also kno...
