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 ...

This program allows the user to encrypt or decrypt any plaintext or ciphertext file, using a random byte key of their choosing, as long as it is between 5 and 256 bytes so it is complaint with the RC4 ...

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 ...

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 ...

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 ...

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.

Microsoft issued advisories informing users they can now disable RC4 in .NET, in addition to additional credential protection for Windows and that it had revoked digital signatures for four UEFI ...

Microsoft released optional security updates Tuesday for various versions of the .NET Framework that prevent the RC4 encryption algorithm from being used in TLS (Transport Layer Security) connections.

Microsoft has warned developers to stop using the RC4 and SHA-1 algorithms. The algorithms have been a source of attacks lately and many have suggested phasing them out, now Redmond has wade in ...
