Abstract: This paper is focused on the synthesis and simulation of RC4 algorithm, which can be implemented on FPGA. A variable length key from 1 to 16 bytes is used by RC4 algorithm to initialize a ...
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 ...
Abstract: RC4 algorithm is a famous stream cipher. It could be used to encrypt images quickly and efficient. However, the RC4 has been proved has some drawbacks, therefore it is considered not secure ...
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 designed by Ron Rivest in 1987. It was widely used in various protocols such as SSL/TLS and WEP/WPA for its simplicity and speed in software. RC4 generates a pseudorandom 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 ...
