This project implements two cryptographic algorithms: RC4, a stream cipher, and AES (Advanced Encryption Standard), a block cipher. Both algorithms are widely used in cryptography for their unique ...

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 is one of the most widely accepted stream cipher on account of its structural simplicity, encryption and decryption speed and efficiency. In this paper, we report on several ...

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 ...

The RC4 and SHA-1 algorithms have taken a lot of hits in recent years, with new attacks popping up on a regular basis. Many security experts and cryptographers have been recommending that vendors ...

A fresh warning concerning the use of RC4 to support secure communication channels online has been issued after researchers were able to exploit the protocol to decrypt user data in mere hours.

Google and Mozilla today announced they’ve settled on a timeframe to permanently deprecate the shaky RC4 encryption algorithm. Google, Microsoft and Mozilla today announced they’ve settled on a ...
