Security researchers have discovered weaknesses that could be exploited to crack some types of encrypted Web communications. The flaw exists in the RC4 encryption algorithm that's often used to help ...

RC4 is a stream cipher and variable-length key algorithm. This algorithm encrypts one byte at a time (or larger units at a time). A key input is a pseudorandom bit generator that produces a stream ...

About time: Microsoft introduced support for the RC4 stream cipher in Windows 2000 as the default authentication algorithm for the Active Directory services. The system has been insecure for even ...

Abstract: The Rivest Cipher 4 (RC4) has been one of the most popular stream ciphers for providing symmetric key encryption, and is now proposed as an efficient cipher within light-weight cryptography.

Abstract: Encryption algorithms are applied to a variety of fields and the security of encryption algorithms depends heavily on the computational infeasibility of exhaustive key-space search. RC4 ...
